The Rising Crust Pizza and Hops

Bought a coupon off a restaurant.com and After getting bill used coupon and the new owner would not accept it. Then she proceeds to lie to me by saying 1. This is for The Crust TO GO not hers, I show her her address on the coupon that was bought that day and then she informs me 2. That she has called multiple times to get off the site then as I pull up the coupon on my phone for her to see the purchase date she says 3. Is there a phone number on there?????? If you've called why are you asking me? She gives me a 10% discount $3 off. I suggested to the server who was very nice that since the owner said she gets 15 of these a day that she might want to put up a sign on her door or windows(which by the way is covered in discounts for apps and drink specials) to let people know BEFORE they order. I understand the issue if she really did call but I don't like being lied to. While she was talking to me another server came over with another tables coupon which she had to decline also.
