A.M.
Yes, definitely! I personally am out about $1000 from people who either did not show up for trips and didn't pay their share OR in one case a couple who went on the whole trip and didnt pay me after. It has happened 3X!!!! So I have decided the bank is closed, and now require payment as soon as people commit.
Hang in there, I know it stinks but some other people just don't have any sense of what it means to be a normal person!
