^^^ THIS^^^ I generally tip $5-10, it depends on the service, the weather etc., I don't care if someone chose that job or it chose them, they have to buy a car, insurance, gas, maintenance on that car. Etc., furthermore, I have had drivers tell me that the brought my orders first because I take care of them, so a 45 minute wait went to 15-20, and I didn't have to go get it.
My wife and I have a local restaurant that we frequent, we tip well when we go, every year @ Christmas, the servers that have waited on us and the hostess's get a card with cash, what do we get? No reservation seating, 45 minute wait, uhmmm no, our table is ready, it does pay to take care of people, period....
