Hello ladies, can I rant a bit please? It's minor but I'm annoyed!
Ok, so every couple of months I get together for a long lunch with some people I used to work with. Since we have no child care, DS comes with me. He is used to formal situations (has been to many meetings, formal dinners in his tiny suit, etc.) and conducts himself very appropriately, much to the shock of the concerned looking patrons at other tables. 
(Disclaimer: I would NOT go if I was ever concerned about his behaviour in these situations!)
Since leaving work, these lunches are the kind of thing that I really have to save up for. Tbh, I will often sell something on ebay so that I can go without it impacting our family budget, which has changed a lot recently.
So at our most recent get together, I was sitting in the middle of the long table with DS on one side of me and a former employee on the other. We had just finished our entrees and were awaiting coffees and dessert. The restaurant owner knows DS and had come out to chat with him so I let him get on with it, whilst I was having a discussion with the person on the other side of me. At the same time, a (new) waitress was beside the owner in their conversation.
Coffees and desserts arrive, including DS' fruit salad. Waitress returns to the kitchen and brings another FULL ENTREE for DS, the same as the one he had just had. He dives in whilst I am asking where that came from and why? Waitress said "he ordered it!" I looked at her, as though she was going to be joking, she wasn't. By the time I get out that I didn't order it and he is not old enough to order things freely for himself, she waves a hand and says "well, he's eaten some of it now so I can't take it back..." and walks away.
I am, putting it mildly, annoyed by this. I became more annoyed upon receiving the bill, which was v. expensive now with the extra entree. However, just as we were about to pay, something rather terrible came up with another of the people I was sitting with and it seemed not the time to start arguing about my bill with the waitress. So I said nothing (not like me) and paid.
If you are still reading this mammoth post, it's an AIBU! AIBU to be annoyed? Or should I have been listening to DS' every word when he was talking with the owner and his waitress? Should a waitress take an order from him without consulting me?
