A simple way is not to get into round buying. I buy for myself and noone else and I don't accpet either.
In fact I get really annoyed with the round buying thing here. If I'm with a couple of good friends then sure but when it is with a crowd then it can get pricey.
The thing is it seems in the UK you should eb obligated to buy a round and if you don't you are a skinflint. If you don't accpet I don't see the problem.
