Example Input: First the waitress was nice. We ordered wings and the waitress they rain out of ranch dressing, how do you run out of ranch! After we waited 40 minutes for our food, the manager told us we the kitchen is behind about 1.5 hours. Also, he did know if they may not fully our order They should have told us how behind they truly was! The food came out cool and not completely done. My stomach hurts and I'm on their toilet, you tell me. Do not visit Never eat here, food is horrible
Example Output: negative

Example Input: I have taken my last ride with Checker Cab. In the past I've tolerated the stinky, dirty, disgusting, worn out cars to get to the airport. On our trip this time to the airport which usually costs between $32-$34 the driver charged us $38. When we questioned him about the higher price he adjusted the price to $34. I can only think that was an intentional attempt to over charge us. They should be offering discounts because their cars are so disgusting. In the future I will take Uber or Lyft. When we travel to other cities in the US the cabs are clean and decent. Atlanta Airport is an international hub to the rest of the world. What a horrible impression we make when one of our guests have to take a cab.
Example Output: negative

Example Input: Great service and wonderful people behind the operation. The visit was quick, painless and professional for my little sister (13 at the time). I've seen my mom deal with too many dentists who overcharge or provide a poor service, treating it more like a car repair than an operation... Dr. Brandon's is different, and I can tell she couldn't be happier. Plus, if my little sister gave a thumbs up, I know it's the place to go. I'd definitely recommend them for any visit :)
