It's quite interesting, the chain of events, reading the original post and your comments. -OP offers snacks. -OP then gets hit up for lunch money, a few bucks. The chain is started. -OP gets hit up for more money. -OP feels guilty because OP had already given the requester money, and so gives more. The chain continues, UNTIL -OP gets hit up for MORE money, and it hits OP's limit. -The requester gets mad because the chain suddenly stops. The requester has been counting on that money, and the requester feels let down.
