What are some cultural faux pas in restaurants? 

As a Customer

• Ask for salt before you have tasted the food. Most chefs acknowledge that food is a matter of taste but don't insult the cook by insisting they got it wrong before tasting it.
• Scream, wave, or snap fingers for the waiter.
• Come drunk.
• Act as if you know food better than the people whose job it is to make and serve it.
• Ask to "see the chef".
• Tell the host or server you're "friends with the chef". You're not. Chefs don't have friends. I kid. But if you were they'd know you.
• Let the open Yelp review input box with the one star ticked sit so that the waiter can see it.
• Wear inappropriate clothing. Most restaurant employees are extremely free spirits. You'd be surprised about the level of debauchery and depravity we're capable of. But we get paid to establish and maintain an illusion for money and you coming in with a t-shirt with some hip slogan into a 2-star restaurant, no matter whom you are (looking at you, Silicon Valley millionaires) screws with our (low paid) job of running that illusion. It's not your free spirit we see, it's your complete disrespect for the low paid wage slave whose work you make harder.
• Send food back because that's "not how I saw it on Chef X's TV show".
• Chew tobacco and spit in your empty water glass (happened a few times to me here in Texas, usually oil millionaires; no t-shirts but they act like children in other ways).
• Dine and dash.
• Have loud conversations about bodily functions, whom you had sex with last night, how your colonoscopy came out, the work of parasites, how there is no god, etc. Keep your voice within your table's confines.
• Come to a restaurant smelling like a garbage dump.
• Talk loudly on your phone.
• Have your kids run around and bump other chairs or trip waiters.
• Make barfing noises or show other ways of disdain with the choice of food of others.
• Trot out how much better you are than the person who serves yo.u

I list many of those as "cultural faux pas" because they might be permissible in some areas (T-Shirts are not a rarity at Coi in SF but would be a huge faux pas in Atlanta or Dallas, hailing a waiter that way is OK in some parts of Italy but not in the U.S., kids running around is expected even in fine dining in Turkey but a no-no in the U.S., etc.)

I'll second talking too loudly on a cell phone, with or without an earpiece.  So annoying.
