Hot take: I think group trips where everyone pays the same are unfair for budgeters

Last month, my friends planned a weekend getaway and insisted on splitting all costs evenly. I was trying to save money, so I skipped some activities and ate cheap meals. When we settled up, I had to pay for things I didn't even do, which felt really wrong. I told them I'd only cover my share, and it got quiet for a minute. But standing my ground meant I stayed on track with my savings goal. Now I push for clear spending rules before any group event. What do you do when friends don't get your budget limits?
