It sounds as if the real issue is that Winn Dixie didn't have enough lanes open. If it truly took 15 minutes to fix the issue that is. I coupon frequently at Publix and very occasionally have an issue with one or two of my coupons. However, they fix the situation very quickly and I've never taken more than a couple of minutes to complete my transaction. I think it is extremely unfair to blame the person that has chosen to use the coupons. If a store accepts coupons, they should be equipped to ring them up quickly and take care of issues in a timely manner. This is on the store, unless the OP chose not to move to a different lane. Then it would be both the stores and the OP's fault.
