Zero.
If someone I know asks me for money, I'm at least asking them "what's up? Everything ok?" before giving them money.
Then after that, still probably zero because I don't have any cash in my wallet atm. So hopefully I can help in some other way, give them a lift somewhere, cover a meal, something.
Knot tying. Most half-hitches tied in 60 seconds or fastest time to tie all six of the "scout knots".
I assume 99% don't know them and I am reasonably quick at them, I could hold the record for at least a day or two.
