Well I did just now! I'll try to make this short. Warm enuff here today to take my WC out. So I went to the store, always take only my Debit card, no wallet. Got up to the register & the girl says "your card is rejected" tried it twice, WTF, come to find out it had expired. I guess I got a new one & forgot to activate it. Was going to leave when she hands me the receipt. I said "what's going on" & some guy had paid it. So I looked around, no one there, finally found him and asked for his name & addy, he said "no" but thanks. WTF I wanted to send him the $$, then some other guy says "just return the favor to someone else, accept it". I did, we shook and he left. "Pay It Forward"??
