I thought I'd come on here to ask and to vent, seeing as it's happened to me not once but twice in a just a few weeks. Both at very highly regarded breweries in the Chicagoland area. The ipad / tablet touch screens where you pay and sign pull up gratuity of 15/20/25%. To me these are excessive, certainly the 20+. Compared to a restaurant where there are numerous servers serving you, cleaning your table, bringing you food, not to mention the cooks cooking the food on the spot. I tip 20-25% after tax regularly with no issue. In addition many will say don't tip that much on the alcohol sales. But at a bar or brewery I usually tip around 10% for just drinks, maybe a bit more. It's different. So both times instead of pushing the button that's in your face almost forcing you to tip high, I custom tip. Both times I custom tip at around 10%. Both times the lady flips the screen, looks at it, doesn't even acknowledge me with no thank you and walks off. That's BS. Do others have this issue? What do you guys tip at brewpubs for drinks only???
