Told waitess I needed to go so if not ready soon Id cancel. She said ready in two mins. was ten more. she was giving refund. manager/'bartender gave me a hard time. no food no refund. they even know my order as a regular. i might have been having a bad night but they chose to lose a customer over maybe cost of 3 bucks. unfortunate
