I'd tolerate them for about three minutes, or until their behaviour becomes unbearable.
Then just accept they're a douchebag and get the hell away from them. If sticking around (because, after all, you have as much right to be there as them, right?) seems likely to cause anger or resentment, then it's better to swallow your pride and at least know you did the decent thing, making every reasonable effort to avoid a confrontation.
If all else fails, a cheap shot to the kidneys will make you feel better.
