Looking for an idiom or expression

[Mehrgan]

Hi everybody,

I wonder if you could give me an informal idiom/expression (British) used for a situation in which one does Sth against one's will (in a friendly situation)...For example, at a party where you hate the meal but you feel if you don't have it the host may get annoyed....tnx in advance...
