Tell Us The #1 Thing Restaurant Customers Should NEVER Do

Snap your fingers at me one more time...

Working in restaurants is hard — and dealing with annoying diners is usually the worst part...

TBH, most of the time these customers don't even realize that they're being annoying.

Like when customers snap their fingers trying to get your attention...

Or when they rip up their coasters and napkins into a million little pieces for you to clean up after...

Or how about those dreaded customers who show up at 10:55 p.m. even though the restaurant closes at 11:00 p.m.

So, dish: Tell us the most annoying things diners do (aka the things that piss you off the most) in the comments below.
