3. "Never refuse to seat three guests because the fourth has not arrived."
Of course, if they had a reservation, it wouldn't matter if the party was incomplete. That table has already been "sold" for a specified amount of time.
But in non-reservation restaurants, it does matter . . . and it's something that guests and restaurant staff will argue over until the end of time

. As a rule, incomplete parties *don't* sit down and start ordering. They sit down and wait . . . and wait . . . for their late guest, and meanwhile, other parties (who may be complete) have to wait for seating. And the table can't turn.
If it's early and there is no wait and the host doesn't expect to start building a wait anytime soon, seating an incomplete party may be appropriate. If there is a wait, then it's a no-no. I wonder how Mr. Buschel will feel about seating incomplete parties when he opens the doors to his restaurant and sees what it does to his average table turns, and therefore his bottom line.
23. "If someone likes a wine, steam the label off the bottle and give it to the guest with the bill. It has the year, the vintner, the importer, etc."
I have worked in restaurants with huge staffs where we had time to do this. Otherwise, it gets written down on a business card. Or the guest writes it down themselves. Is he serious? Has he ever had to do this? It takes a fair amount of concentration and time to do it properly. Perhaps when he opens his restaurant, and his staff is running around like chickens with their heads cut off, he can be the calm island in the center of the storm, steaming labels off bottles like the very picture of Restaurant Zen.
42. "Do not compliment a guest's attire or hairdo or makeup. You are insulting someone else."
I'm sorry, but this is bullshit. In other arenas of life, are we allowed to compliment one person and not another? I would not compliment one lady (oh wait, I can't call them "ladies," see #39) in a group of ladies, but I routinely compliment the ladies who are obviously on a Big Date Night and nervous. A sincere compliment on a dress or a bag puts people at ease and helps make them comfortable--I have seen it happen. Gasp! Because, unlike Mr. Buschel seems to think, many service professionals are very able to read a situation and interject just the right amount of "personality" to help make our guests comfortable and happy. That is part of our job.
There is no other industry where people have so many well-aired opinions about how its workers should do their jobs. None. We know we are under a microscope every night, and most of us have our own internal list of rules that keeps us on point and our guests happy--but we are not robots. So while some of his "rules" are legitimate, I hope that after a year or two in the business Mr. Buschel will be willing to revise others. He may have a hard time retaining staff otherwise.
