Is it a lack of knowing or a lack of caring? Tips in Restaurants

I am going to take a brief moment to vent and educate about the ettiquette of tipping. I would first like to say that it is something you should do. Until I worked in the restaurant industry, I never really knew how important it really is. Recieving a $0.00 paycheck twice a month does not exactly pay the bills. The meager $2.45 or whatever it is we recieve is taken away by taxes with every paycheck. So saying our lives fully depend on your tips is not an exaggeration.
I am going to do a quick run through of the things I as a server do and we will see how much is really over looked.
Scenerio: Customer sits down at table. "Hi my name is Apryl and I will be taking care of you this evening, what can I start you out with to drink?"
Run to the back to get drinks. Ring them up in the computer under their assigned table number. Make sure each drink matches the seat number. (Person on left is seat 1)
"Would you like any appetizers this evening?"
If yes, ring that up. Then put together a bread setup. (One loaf of bread with a plate of herbs and a knife.) If no, jump right to bread. Take that to the table, pour olive oil on herbs.
"Are you ready to order yet?"
Take order, make sure to keep seat numbers in mind.
Put the order in the computer.
Take food out. Ask if they would like parm (cheese) grated on their dish. Of course they do, just bring the stupid cheese with you because nobody says no.
Let them eat, ask if they would like dessert, if no, ask if they are one check.
Print checks and deliever.

Easy enough. BUT, here are the things you, the customer, don't see going on. That bread we bring you, we have to make. We have to oil it, salt it, bske it... everything. The silverware you're eating with, we polish and roll them. The table you're eating on, we wipe down and set up probably 10 times a day. Just that one table. ALSO, people are ordering ToGo. We take care of that as well. We put their food in togo boxes, get them bread, put it in bags and check them out.
Sounds easy enough, but not when you have 3 ToGos and 3 tables all not remembering that they are not your only table or ToGo.

So, if it was a lack of knowing, you've no excuse now, because you've been informed. If it was a lack of caring.... then that's fine. But do not be that table that has a server running all over the restaurant for a $2 tip.

%10 tip we look at as you had a medeocre time. It was fine and you wont be rude and not tip, but you won't give more than bare minimum.
15% we see as good. You enjoyed everything and it was a good experince. You may come back again, it wasn't anything special but just good.
%20 is really good. We are very appreciative of %20 and think you really enjoyed having us as your server.

Anything above 20% is a day maker. The kind of tip that as soon as you walk out the door I am dancing and showing my co-workers and hoping you come back soon and ask for me.

Well, that's my spill.
