I've just endured a meal with the inlaws and fil insisted on rounding the bill up - not to the nearest £10 but to the nearest £20 before splitting it out evenly between us all.
The meal was a set price the only thing that varied it was the drinks.
DH and I only had enough money for our share of the bill (tight month) and yet FIL would not accept this and nearly started a row saying we should pay the extra as it was for a tip, the service was shit tbh and didn't deserve one.
AIBU to be angry with FIL for insisting we spend more money than we had budgeted for a)because he got pissed as a fart and most of the bill was his drinks and b) for him rounding it up without asking
How do you deal with group meals and splitting the bill? This has really upset me as I'm now utterly skint
