As a general analogy, to nobody in particular other than those happening on this thread. Another bit of role playing. Let's say you have your day job but for many years you've enjoyed cooking, to the point where your pies are good enough to sell. With that in mind each Sunday you set out a little stall in the local market. One day, a sharply dressed geezer parks his Audi on the curb and wanders over to you:
Businessman: "I just want to tell you those pies look fantastic - amongst the best I've seen, you really are an awesome cook. Would you mind letting me have three of them?"
Baker: "Thanks for the compliment, they're five pounds each"
Businessman: "Sorry, I didn't make myself clear. I don't have a budget to pay for the pies, I was hoping you would donate them"
Baker: " Why would I donate them to you?"
Businessman: "Because you clearly really enjoy making pies, like a lot of people - cookery is one of our national past times after all, just like photography in fact. Are you telling me you always expect to get paid?"
Baker: "When I'm dealing with a stranger promoting and selling something, yes"
Businessman: "I'm afraid we don't have a budget for food when we're on business. We're trying to increase our profits as much as possible, a lot of the people we ask will give us something to help us out - after all, we need quite a lot of energy to get through our business day while we're out and about selling our goods. I think it's cool that there are so many stupid numpties out there who respond to a bit of flattery. We do meet the odd awkward stuck up b*gger who won't play ball though - what makes you think you deserve something in exchange?"
Baker: "Well, the fact that I've been practising my baking for a lot of years in order to get it to this standard, actually I went to college. I use the best ingredients and I have a decent oven, which costs money. It also takes time to go and choose the ingredients and then do all the mixing, styling, and cooking which takes electricity. Then I have the overheads of running my pitch".
Businessman: " So you're not prepared to do something nice for someone else?"
Baker: " On the contrary, these pies help to feed my family and pay bills - and I share them with my friends, which is definitely nice. The ones which don't get eaten are delivered to my favourite charity"
Businessman: "But if you give us some pies we'll tell people you made them - it might get your pies out there"
Baker: " And the people you tell probably don't eat pies, or they're other business people just like you wanting a freebie. Look, I'll give you the pies if you give me one of the plates you're selling"
Businessman: "You have no idea of how businesses get food these days - it's a one way deal, or nothing. I can't give you any plates, we don't give our products away - we're a small enterprise"
Baker: "Oh, right. So why would I give a stranger something valuable, which has cost me time and money to create, when I will get absolutely nothing in exchange?"
Businessman: "err, ermm, huh, oh f*ck, because some other people will, so you might as well"
Baker: "so why don't you go and ask those people instead?"
Businessman: "because your pies are the ones we want, they will make us and our business look really good"
Baker: "ever thought of baking your own pies?"
Businessman: "Christ no, we don't have the skills, or the money for the equipment - that's what dumb-ass bakers are for"
