The school gave us a .50 cents off coupon to Subway for selling a lot at a fundraiser. When I used the coupon at the above Subway, I noticed that my charges were higher than purchasing without a coupon. I asked the cashier if a mistake had been made. She said no. Customers pay more when they use a coupon (does that make sense to any body?) I asked her why she didn't explained that to me before using the coupon. She said it was against company policy. Of course, they rip you off. I told her to refund and charge me regular price and she said she had already made the transaction; therefore, I ended up paying more with a coupon rewarding me for the great job I did selling.
