Anytime you have to look for them to get something

According to you one should just stand by the table so your highness won't have want or wait.
People like you who want the server's undivided attention are worse than the bad tippers.
Back in the day, I would have much preferred someone who was polite and understood I couldn't be everywhere at once than someone who felt their "big" tip entitled them to anything more than my usual excellent level of service.
Tipping is something that comes at the end of the meal to express satisfaction and say thank you. To put money up front and say 'let's see how much of this you get to keep' is insulting. Most people are completely unaware of what a PITA they become once they sit at a table. Every little picayune like, dislike and fetish comes to the surface.
Nitpickers aside, people generally are just as one would imagine and I had the pleasure of serving many excellent and interesting people over the years. Never a dull moment and you get all kinds...Cleavon Little once tipped me $20 for bringing him a ginger ale, Judd Hirsch dumped his Canadian change in with the tip, and Roberta Flack was rude and snobby and walked out without paying the check or leaving a tip.

No, but then again, I don't want to wait till the end of the meal for someone to freshen my coffee either.
I don't want the wait staffs undivided attention. I realize that there are other paying patrons.
I would like them to, perhaps after serving someone else, stop for a second and say, "Is there anything else I can get you?", instead of walking by without even acknowledging my existence.
