Eats me up

The NYT has a list of do's and dont's for restaurant staff.
It has prompted more than 1000 comments (some really nasty ones from disgruntled servers).
Do not get me started on restaurants in NY.
Since the crisis, I think the attitude problems have gotten a little better. Now you don't have to feel like some establishments are doing you a favor by you spending money in them. I have never understood how in a city where there is a good restaurant or more on almost every block, restaurants can afford to treat diners with attitude.
My favorite evil thing restaurants here do is:
"3. Never refuse to seat three guests because a fourth has not yet arrived".
This drives me absolutely insane. It is not welcoming.
Other stuff that drives me insane:
• No one to greet you at the door, but you can't take a table by yourself.
• Idiot hostesses or hosts (especially if they are good looking and useless, like at Coffee Shop in Union Square).
• Reserved tables for no one in particular, just for hype (see above).
• A restaurant full of empty tables and an idiot who asks you for a reservation.
• Empty tables and a line of hungry people outside.
• No smiles.
• Asking for the bill three times (Dim Sum Go Go. Great food, lousy service).
• Asking for tap water and never getting it (Yes you, Bar Pitti).
• When waiters cannot hide their frustration/disappointment/contempt if you only order tap water, or if you order from the cheap stuff.
• "Do you need change?" Who am I, Warren Buffett?
• Restaurants with bouncers.
• Bad food.
