I will not visit your location again.  You do not honor your coupons.  There were two times I gave the register worker a coupon and they were not applied to a drive thru order.  Both times valid coupons were used, and one instance was greeted with negativity and the response that I did not need to use a coupon.  The price on the menu does not include the coupon.  I will not bring my money to your establishment if you do not honor your own advertising.
