"Friday, off the cuff walk past. Looked OK, not too busy so thought I'd try it. Quick service initially then started to get busy. As I was on a table for 4 I offered to move to table for 2, well blinked and food had been moved. I finished and paid, to find 10% discretionary change added which was advertised admittedly.Thought I might of been let off as I offered to move and free up a bigger table No, didn't even get a thank you. The foods good so ill be back, but I certainly won't offer to help out next time, oh and could try smiling occasionally"
