Example Input: Me and my boyfriend just left Gino's and had one of our worst dining experiences. The couple seated behind us were having a similar experience and at least provided us with some comic relief. It took about 15 min for our server to bring menus but when se did, she apologized. She took our order, didn't write anything down then came back and asked us what we ordered again. She brought 2 waters even though my boyfriend had asked for iced tea, about 15 minutes later brought our salads then came BACK and asked what we were waiting on so she could look out for it. Our 2 slices of pizza came another 15 minutes later like warm and not very flavorful. The couple behind us had to refill their own drinks and go searching for silver wear. After finishing our food and not being brought our check we went to the counter to pay, where the server had to wait for another woman to finish taking to-go orders and helping customers before she could get change for us. So much for grabbing a quick dinner. We were there for an hour.
Example Output: negative

Example Input: My family and I walked in Friday night (11/3/17). Friday nights are typically pretty busy at pizza parlors. I get it. The thing is, there was no line at the counter, and several tables were open. It wasnt that busy. I go up to the counter to order and the girl asked 'Have you already ordered?' I told her no. She said 'Our kitchen is really backed up with orders and its going to be at least an hour wait.' A guy behind her back in the kitchen chimed in 'At least an hour.' I told her, 'Ok, well probably just skip it.' Her demeanor quickly went from unhappy and stressed to relieved and smiling when she heard this. If I was the owner or the manager of this place, I would be pretty angry and concerned that my staff was persuading patrons not to order at the counter. They lost out on my $60.
