We received coupons in the mail for KFC. 7 pieces of chicken 14.99. My wife presented the coupon and was accused of making the coupon. Person at counter said no it will cost 23.10. 1. What how do you make a coupon when it came in the mail. 2. Is this the scam bring in coupon go to order say it fake and most people just say charge me. This is KFC in Spanaway Washington. Very disappointing
