I witnessed the following exchange in a tearoom last year (not one of mine i hasten to add) - the customer was in front of me in the queue
Customer : Could I buy a single biscuit please
Assistant: No we only sell plates of 6 biscuits
Customer : look, my father is having chemo, he says a plate of 6 will make him feel sick, so could he just have a single one
Assistant: No we only sell them in sixes
Customer ; I'm happy to pay for a plate of 6, but can I just have one and leave the other 5 with you
Assistant : No, I've already said we only sell them in sixes
Customer : Fine, give me a plate of 6 , I'll just save the other 5 for later
Assistant: we can't let you do that , all food has to be consumed on the premises
Customer : *exasperated* fine i'll just throw the other 5 away
Assistant : We can't do that sir, just leave them on the plate if you dont want them
Customer :have you not listened to a word i've said ?
At this point I couldn't take anymore, and interceded, and bought a plate of 6 biscuits, and gave the other customer one of them :shake:
