When you are through giving away and drinking the free sodas that you brought to the meet, some people are willing to save you a buck's worth of gas to drive and pay more for something cold to drink........

No one forces a person to drink free and no one forces someone to
pay for something they don't want.

I want to point out that I am also donating items to help make the BBQ
a success, as I frequently do at meets, and haven't yet seen what you are donating.-Bob

If you want to borrow a ski mask to collect free "donations" from
a convenience store, maybe someone will loan you one........
.........for free..... LOL
