I like to tip $1-3 dollars depending on how quick they serve
41 And whosoever shall compel thee to go a mile, go with him twain.
3 Know ye not that we shall judge angels? how much more things that pertain to this life?
The difference is that servers are being paid like $2/hour plus tips, while the Starbucks (or *insert fast food place here*) drive-thru worker is making $10-18/hour
I dont always get prompted at every starbucks I go to. If I do maybe like 50 cents. If its a busy area, 50 cents from most customers can go a long way...then again I imagine most people do not tip there, and I dont blame them.
