Goodwill Good Career Center

Today I was at the goodwill location on Dolorosa downtown. I thought I had found 2 great deals. But when I got to the register I gave the cashier my items an I had my parking ticket in my hand an she told be I can't stamp your ticket bc your total is $3.78 an it has to be $5.00 n over. I felt very embarrassed n uncomfortable bc the customer behind me were staring. So I had to leave my items. I just hope the headquarters would take this into consideration that if we have a purchase we shouldn't have to pay parking.
