OK...went in coupon in hand. $6.99 for any footlong. Ordered sub, get to check out, cashier says "our system is glitchy, coupon might not work." And it didn't. So I end up paying $8.60. Now I should have said something, but I did not. First, she saw I had coupons in my hand when I ordered, should have said something then. Second, what happened to customer service? OK coupons not working, here's a cookie or a free drink, or a free bag of chips. Don't people realize the difference that makes? Lost a customer for life. Did not have to happen.
