I'm adding a trendy sushi place to my list. We went there for my husband's birthday, with friends, and the service was truly appalling.
We had several drinks (water, soda, alcohol) and no coasters, so the table had condensation all over it. They gave us one sushi menu. For four people. We spent 15 minutes passing it around before we could get the waitress to bring us more. So finally we all wrote our sushi orders, and they got pretty wet because of the water all over the table. We hand them to the waitress, who puts in the order and then puts the papers back on our table.
So our food comes out, there's some rolls that we ordered and some that we didn't. When we said "We didn't order that", the waitress's response was "Yes you did."
We convinced the waitress to look at the sushi papers, which were now soaked. One was missing, and in its place was an order that wasn't ours. The waitress first insisted that it was the correct order, but finally relented and had my friend give her her order verbally.
She returned with the two rolls my friend had ordered, plus a shrimp tempura roll. My friend insisted that she had not ordered the shrimp tempura roll, the waitress insisted that she had. No proof, since the sushi paper had been lost (although why a diner should have to provide proof of what they ordered, I do not know) so the waitress went back to the kitchen.
She returned with a brand new, completely dry sushi menu (remember ours had been soaked by the condensation) on which the two rolls plus the shrimp tempura were marked. It was absurdly obvious that the waitress had simply filled out a new menu to present as "proof" that my friend had ordered the shrimp tempura.
I ended up just paying for it because I was too ticked off to keep arguing with the waitress.
That was the lowest tip I have ever left in my life. I also contacted corporate and posted about it on review sites.
