Do you pay for others meals/activities or do you have each person pay their own way? BIL was talking about dates for his daughters party in a few weeks and also mentioned he's not providing for everyone. I didn't pry but I really hope he changes his plans of venue (he was up in the air, think crazy busy, pricey kids zone) or at least lets people know ahead of time so that they can plan ahead.

We had a party at a venue type place and paid for everyone's food. Wondering what the norm is where you live, or if it's just individual preference. If you don't pay, how do you inform others? Or is it tacky to assume a host would pay anyway and do you just bring enough money to cover what you would need?
