Sam’s Tavern Belltown automatic 40% gratuity

Super annoyed about last night at Sam’s Tavern. Never going there again and they did not state anywhere that it will be a 40% gratuity… also annoying as “portion retained by business” is most likely going straight to the owners pockets. I paid for the privilege of eating and drinking at the owners bar. Been going for the past 5-6 years and won’t be going again. Also I believe their manager showed up last night for their shift as they were not able to put the BMF UFC fight on the big screen…
