Just come back from a week away, 3 of us mostly but with another joining us for a couple of days.
two of us (and random joining friend) were happy to have a kitty. So bung a random amount in and pay for entrance fees, food and drink out of that.
If anyone was going particularly over the top that could be reflected in a bit more being bunged in or in the divvying up of any refund at the end.
4th friend wanted to keep a copy of every receipt, write who was at the table for the food. And has just now worked out what we owe.
It's not plate by plate - but a 1/3 or a 1/4 of a bill and I think she has made some allowances for if I was just having a beer and everyone else was having cocktails or such like.
I appreciate the effort she's gone to - but I have to say AIBU in just thinking a kitty and a bit of give and take is easier!?
