At a kids party recently and the outlaws were there. The outlaws have a reputation for being tight as a badgers arse, particularly FIL. At said party (which was at a gym) I asked FIL if there was anywhere to get a tea, he said no, only a machine.
Forty minutes later he has gone to said machine and bought tea for him and MIL, didn't even offer me! (I would have paid for my own!)
So WIBU to go round there at Christmas, take nothing bar presents, eat them out of house and home, drink their alcohol and take all the leftovers for the cat?
