Just do it, yo.
Disclaimer: I’ve never delivered pizzas. I used to not tip when I lived on campus … DUMB. When I moved off campus, I realized one day that I should tip.
Nowadays, I get awesome service. I know that because the regular driver who delivers to our apartment complex on weeknights is always smiling before I even open the door, and his “How are you tonight, Mr. Morris?” isn’t fake. I think Leonard tips the guy well, too, because he’s mentioned him favorably, too.
Heck, if we go a couple weeks without ordering a pizza, he’s said, “Man, did y’all go on vacation or something?”
Speaking of pizza, I have five slices in the fridge. Time to head home.
