This was a while ago while I was a senior in high school when I had friends over for July 4th. (about 15 people) the plan was to grill and play some drinking games. So I bought around 40 dollars worth of food (mostly hamburgers and chips) beforehand by myself and afterwards I asked everyone to pitch in a few bucks each to help cover the cost.

To be fair I didn't tell them I was going to expect them to pitch in but it was a set precedent for previous times when my friends and I would grill brats so I figured this would be no different.

Only like 5 people ended up paying me so I was out 30 bucks and everyone seemed mad at me for asking.
