Friends who invite themselves over, along with their 4 kids, and then leave you to pick up the tab for all the food.

Why the fuck would you do that?
Then turn around and be like..........."oh, I only have 30 left, will that be enough to chip in?"...............when the shopping bill is well over £200.

To make matters worse you can be damn fucking sure that by the time she gets here later today she won't even have that 30 left because something else would have come up.

Maybe I just hate what a mug I am.
I hate people who stand there are let you pay for everything without making any god damn effort to at least offer.
