While waiting on our flight we went to this restaurant to grab a bite to eat and because there were no signs directing anyone to the appropriate place to order, we mistakenly ordered our pizza from the take-out register. Upon noticing this, we decided to go into the restaurant to sit down and eat our pizza. When we tried to explain to the waitress our mistake she presented us with an "eye roll" and then turned her back on us and walked away. The entire time we were trying to order our pizza, the cashier and another employee were talking to each other. Before walking in to the restaurant we tried to get the attention of one of two waitresses standing at the entrance so we could tell them what we had done. They also could not stop talking to each other long enough to even look at us, let alone ask us if we needed anything. My husband and I eat out a lot and have never been treated in such a rude manner by so many people in one place. I don't think I've ever seen anything like this before. Needless to say, we will never go back. It's a shame this restaurant does not have some kind of management on site to complain to.
