Thanks everyone for the words of support.
We got on really well today - nerves settled down once we got started and I think we've come away with some good shots.
The official tog seemed like a nice bloke - his wife (the boss) was terrible. I'd had a little chat with him about the light and things and she'd been giving us filthy looks. I stayed out of the way whilst they were taking their structured shots, the bride arrived and they had no shots planned of her getting out of the car so I stepped up to take some, and he moved into shot...oh well he probably didn't realise I was there - nevermind.
I left a lot of the shots alone because I didn't think it was fair to the official tog/and the shot was one they would have anyway until it came to the ones with the car in the background - it was something I wouldn't be able to replicate later in the day but rather than getting a shot of what they were taking, I'd take half of the photo - so the bride and groom rather than the bride, groom and bridesmaids - just for something different.
I did this twice and stood behind and to the side of the tog, well out of his way. Sue had already had a nice chat with her and had said that we didn't want to get in the way, etc - being really nice - at this time, sue was in the room for the ceremony and I was outside getting arrival shots...anyway - After these two shots his wife approached me and said "would you mind not copying out shots please?"
It wasn't a nice question either - there was a lot of snobbishness and nastyness in the question - probably because of the size of the 30d/grip/580ex/fong - it looks like a monster.
I replied with "I'm in a public place and I can take pictures of what I like, thank you very much" - A little nasty of me I know, but she'd p***ed me off (its amazing how easy it is to do that to me at the moment). So she carried on "well, they're paying for the poses blah de blah" - and I said well yeah, they've already paid for them, I'm just trying to get additional shots to complement what they're getting from you. The bride then chipped in and said she wanted me to be able to take shots but she wasn't having any of it - I backed down completely (I didn't want her day ruined after all) and I left them to it.
Once I'd stopped taking photos she was nice as pie, chatting to me, asking if I did it as a hobby, etc. Talked about working together and how they wouldn't get in the way of any shots we were taking. And how I could take shots once we were round the back because everyone takes shots there.
I let them go off into the room and the ceremony took place and I was busy getting shots of the reception room whilst it was nice and empty. After they'd come out, I purposefully stood out of the way and didn't take photos - I didn't want any additional confrontation and they were just that way out. Sue did take some of the shots (after all, she'd only asked me not to take any shots

) There was another lady there with a fuji compact with a fixed lens who was also taking shots with us.
Apparently in the ceremony the wife had been looking at the mirror at the front and had moved in the way of anyone attempting to take a photo - when we were out in the garden at the back she attempted the same. So much for working together professionally
Some of the lighting positions they used with the bride sitting on the grass in bright sunshine I wouldn't have dared attempt (metering nightmare).
I came away with some usual shots but was frustrated that I didn't get access to the shots I wanted to take - at our wedding last year the tog had no problems whatsoever with people standing next to him taking what he was taking and he was a lovely bloke.
I don't think I'd be able to be secondary photographer at a wedding again, but I think we could handle the setup on our own - our tog did lots of things with hands and the way the dress fell and things like that - these just told them where to stand.
Oh and the reason they were only getting 36 shots?............the tog was shooting on a minolta film body - even more of a nightmare for that metering (blown out dress anyone?). At least with digital you can see whats going on if you've taken a shot - unless he's just that good that he knows whats going to come out of the camera rain or shine. The bride's mother also said they didn't get a contract/invoice and wanted paying cash (tax dodging anyone?). Oh well, thats enough of a slating, we'll judge them by their pictures when they come back, I just hope they've done the lovely couple justice.
I felt a lot more relaxed once they'd gone, and was able to get around and do what I wanted - Sue felt the same.
All in all a great day out and it didn't feel like work - we got to soak up the atmosphere and enjoy it, it was also fun because its the first wedding we've been to since we got married last year
Cards were out by the guestbook and we've had a few people asking about portraits so we'll see how we get on.
