I'm pessimistic about this. How much do you think these people will get tipped ( total percentage ) thru the course of a day ? Why am I pessimistic ? Who eats Mickey D ?....and why ? Is this demographic inclined to tip 20% ?..15% ?....10% ?....5% ? Sorry, not much .....from what I've seen........and calling for a delivery ain't gonna change it. I think it would better safer + more prosperous BEHIND the counter.
