1. Being subjected to having to listen to fairly loud cellphone conversations at the next table. A glare is appropriate. Know this is not the fault of the restaurant, but topic here IS "restaurant pet peeves".
2. One more vote for the "How are YOU GUYS?", especially when it comes from the mouth of a toddler young enough to be my grandchild. As irritating as pulling a popsicle stick across my teeth!
3. Not showing tea/softdrink prices on the menu, and finding them to be almost on par with a mixed drink on your bill. Since when is iced tea worth $2.25, especially when the wife ends up drinking half a glass?
4. Agree with being adverse to the wait staff rushing to to remove dishes from under my nose. Hey...leaving such on the table doesn't bother me, unless of course I am ordering dessert.
5. Being seated a table that is in very close proximity to the service station area, or the entry to the kitchen...should even have tables placed there. What atmosphere!
6. And my all time favorite...finding multiple mistakes on my bill.
