I laughed. I am totally going to open up this tavern with that exact name. "You want an ale with that potato asshat?"
"Bartender, the milk is curdled." "Then don't drink it dummy." The customer service will be atrocious. Plates will be thrown and prices will be inflated. lol
The funny part is I bet this tavern would be moderately successful as a business model. Questionable Content an online webcomic has "Coffee Shop of Doom" which has this model. In Chicago Ed Debevic's basically operates on this principle. The servers all insult the customers and people love it.
