I earned a free $5 gift certificate from my work the other day for a job well done, yay! I walked down the street to Subway. I had to wait about ten minutes there were so many people there! I finally got my food and went to pay, and I handed the cashier my gift certificate and my debit card for the difference. As I was signing my receipt, I notice it's for the the full ammount. The cashier says "Oh, I didn't know you wanted to USE your gift certificate." Nope, I just wanted you to see it so you know I have one!!! They would not give me a refund because it had already rang through. Pretty stupid.
