Pizza Hut

I received an email from pizzahut.com about a, 1 large 1-topping pizza for $5.99, dine-in only. The coupon specifically states "Print this email or show phone to server to receive this special offer." I visited this location with my 9 year old nice who was visiting our of town for a quick bite before heading to the pool for swimming, and of course to take advantage of this great deal. As I proceeded to the counter to ask about seating I was told that this location was self-service, that they had no servers, and that I would have to order at the counter, seat myself & get my own food/drinks. Now I know the different between a carryout/delivery Pizza Hut vs a sit down and eat-in Pizza Hut restaurant, and the setup of this location is definitely a sit down and eat because of the large dining room. Before ordering my pizza I told the manager Jose (who seemed to be the only employee working there on a Saturday afternoon) about the coupon, showed it to him on my phone and he told me he could not accept it because it wasn't printed. He suggested I go home print it and come back despite what the coupon said.I told him I had no printer at home and that the coupon lstates I can show it to you on my phone. Not only did he refuse to honor my Pizza Hut coupon but he was extremely rude. I am shocked that this person is a manager. At one point he stated "I can't help you" & retreated to the back to avoid answering anymore of my questions. When I asked for his District Manager's name and phone I was told by Jose that he didn't have it and that I'd have to get it off the website. I will say this, he did give me the store number, even though i could have retrieved it from the website as well. This is UNACCEPTABLE! Within a 3-4miles radius there is also a Little Caesar's, Papa Johns, Dominos, another Pizza Hut, and a few non-chain pizzerias. One would think that this location would be a little more respectable and value their customers. As a long time pizza hut consumer I was very disappointed by this location. Let me please state that I have ordered carryout and delivery from this location before and the pizza was good, like most pizza hut pizza I've had. This review is base solely on my individual poor customer service experience.
