Input: Consider Input: Terrible. Made an appointment the day before to have a car towed from one location to another. It was the beginning of a holiday weekend, so timing was urgent to get there before they closed. After not hearing from them, I called them in the afternoon. He supposedly had trouble with his truck and was going to send someone else. Just got a call from the backup driver...he knew absolutely nothing and had just gotten an urgent call for a tow. He (the second driver) thought I was stranded somewhere. So now, after a no show, no call, it is too late for the car to be towed in time for anything to get done. Will never call them again...

Output: negative

Input: Consider Input: Good experience at Barista: nice ambiance, good service. However, the coffee was a bit underwhelming and in my opinion a bit overpriced for the quality.

Output: positive

Input: Consider Input: I joined yelp just so I could comment on the Union Sq. Clinic. I just came back from my appointment with my cat and I am pissed! The vet recommended an invasive exploratory surgery for something other vets have said is not necessary. My cat has already been through a major surgery ( a few years back for cancer), so I don't want to put her through one again unless it was absolutely necessary. When I asked if there was a less invasive option to see if surgery even would help, she basically told me if my cat got cancer it would be my fault. Wow! I will never go back there again if she is still on staff.
Output: negative
