I have been previously warned about the service at Aces & Ales being average. But I love trying new beers. We went after I bought a Groupon and so we went. The service was okay and the second shifts came in and were very friendly. We ordered, ate and drank for a good two hours. When it was time to leave, we gave our bartender a $20 for tip because to our surprise she was great. We paid and left. The next day I noticed a 20% tip added to my amount. I called to speak to a manager and ended speaking to the bartender from our visit. I asked if there was an automatic tip charge on each bill. She said no and I left a message for the manager. The next day the charge was corrected and I received a call from the manager. He explained that some backs automatically put a 20% charge on tickets. WTF! This guy must think people are idiots. I let him speak and was trying to hold back my inner thoughts. I will probably not go back. So if you go to this bar definitely pay with cash.
