It's a hobby. When I stop trusting you, it stops being fun.
FWIW...they probably didn't intend to stiff you. They probably just forgot,
and now that it's been so long, they're too embarrassed to even speak to you.
Irresponsibility and procrastination, not malice.
That's why ask for payment in advance (preferably PayPal). IME, it preserves
friendships. Even if *I* don't mind getting stiffed, *they* feel so guilty
about it they slink off, and never post again.
