Why is it "cool" to tip at Starbucks or any other "in" place to get your coffee, why do their employees deserve a tip than those at any other fast food place, I doubt anyone tips at McDonalds, Burger King, Tim Horton's or any other fast food restaurant, and that is what Starbucks is, just a fast food coffee joint.
Cool? What...are we kids in school?
If you want to tip, do so. I don't tip at Starbucks, Dunkin Donuts or any like establishment.
