Including.... 1. Do not let anyone enter the restaurant without a warm greeting.
2. Do not make a singleton feel bad. Do not say, “Are you waiting for someone?” Ask for a reservation. Ask if he or she would like to sit at the bar.
3. Never refuse to seat three guests because a fourth has not yet arrived.
7. Do not announce your name. No jokes, no flirting, no cuteness.
8. Do not interrupt a conversation. For any reason. Especially not to recite specials. Wait for the right moment.
9. Do not recite the specials too fast or robotically or dramatically. It is not a soliloquy. This is not an audition.
12. Do not touch the rim of a water glass. Or any other glass.
14. When you ask, “How’s everything?” or “How was the meal?” listen to the answer and fix whatever is not right.
15. Never say “I don’t know” to any question without following with, “I’ll find out.”
21. Never serve anything that looks creepy or runny or wrong.
25. Make sure the glasses are clean. Inspect them before placing them on the table.
27. For red wine, ask if the guests want to pour their own or prefer the waiter to pour.
28. Do not put your hands all over the spout of a wine bottle while removing the cork.
31. Never remove a plate full of food without asking what went wrong. Obviously, something went wrong.
34. Do not have a personal conversation with another server within earshot of customers.
35. Do not eat or drink in plain view of guests.
36. Never reek from perfume or cigarettes. People want to smell the food and beverage.
38. Do not call a guy a “dude.”
39. Do not call a woman “lady.”
40. Never say, “Good choice,” implying that other choices are bad.
45. Do not curse, no matter how young or hip the guests.
47. Do not gossip about co-workers or guests within earshot of guests.
49. Never mention the tip, unless asked.
50. Do not turn on the charm when it’s tip time. Be consistent throughout.
