We had one woman like this everyone called "dime bag Debbie" because she always asked for "ten dollars for chicken"

Not happy (but still accepting) if you gave her anything other than $10, and a few people I knew apparently tried to buy her raw and cooked chicken, as well as chicken sandwiches from various restaurants and that was also unhappily accepted.

I think the $10 thing is a coincidence, and people call her "dimebag" because they assume she does drugs. No idea if she does or not though.
