We tip because women are predominantly the ones with those jobs.
Women are equal to men in every way...so therefore must be tipped and given extra help.
They will have to go back to whoring if you don't tip.....and you don't want that. Do ya?
At the afore mentioned restaurant my wife and I attend weekly there was once a couple (male/female) of college students working there. The girl who was nice looking told us she more than doubled her boyfriend in tips received.
