DP and I collectively earn about 15 times what DP's younger siblings earn (they don't know how much we actually earn except that it is a lot).
The youngest once asked us to book some London theatre tickets for him for when he came to visit with his GF (she had never been to a West End musical). We bought tickets for him and for us, thinking that he would pay us back later for his.
His tickets came to about £80 and when he showed no signs of offering up the money we thought that he would offer to pay for dinner. He didn't even bother to pay for his half of dinner let alone offer to pay for the drinks. During dinner his GF coo-ed about how the tickets were a birthday present from him. He just sat there and smiled.
As I said, we earn about 15 times his salary so we don't mind picking up the bill for dinner. He is DP's little brother in London and we we meeting his GF (and now wife) for the first time so we were glad to play host. But it was taking the piss to expect us to pay for his theatre tickets especially when it was supposed to a birthday present from him to her.
Anyway, now whenever he or his brother suggest meeting up we just fob them off. On the occassions when they come to visit we just ignore the hints to go out for dinner and instead we just order pizza or kebabs.
They aren't cheap or tight judging by the money they spend drinking and partying. They just think that DP and, by marriage, I owe it to them to pay for everything simply because we are related and have more money.
Sorry for hijacking the thread. I just wanted to vent (he came to stay last weekend)
