I am the owner and the manager.
THEY ARE THE REASON PEOPLE COME BACK, EVEN IF THE FOOD IS MEDIOCRE THAT NIGHT.
I don't agree, but a good wait staff is very important. Wait staff always consider themselves the most important part of the restaurant. Ego. I wish all establishments would work as a team, but that is a wish.
I don't agree with some of the information you've posted, but I don't have the time to play games. "hospitality" is in quotes because it's ironic to me that the word contains hospital. I also know a lot of nurses, but that's another story.
Not everyone in the service industry is a tip whore. There's just those few, who give the rest of us a bad image.

PS. My bus boys speak better English than the waitresses. And if I were having a bad day, I would not take it out on a customer. A porter, a gate agent, a FA, wait people, or ANYONE should also be nice to others. Just because you have a lousy day is not a reason to step on everyone else's day.
