Input: So incredibly disappointed. I went to get a gel manicure and as soon as I left the salon my nails started to darken, and it almost looked like they were burnt. It seems that she may have left my nails under the UV light for too long. I'm not the type of person to demand a refund, but I definitively will not be going back.
Output:
negative
