Moving into a new neighborhood with my girlfriend. We each lived in different parts of town and worked different schedules, so each arranged for separate moves. I had just finished unloading my stuff. Friendly neighbor walked over to say hello. We started chatting. Nice guy.
At some point, he mentioned something about having to head home for a pizza party. Checked his wallet and he was short. We all know where this is heading so I'll skip to the end. It only cost me $40. Never saw him again.
When I was younger I read somewhere “If you give someone $20 and never see them again, it was probably worth it.” Accounting for inflation I think that perfectly fits your situation.
