Let’s be clear: this was a super gross thing for this guy to do, and he shouldn’t have done it.
On the flip-side, if you don’t have enough money to tip, don’t order your pizza for delivery. Go pick it up, do something else, because just like waiters, drivers deserve to be tipped!
We guess what we’re saying is, while the guys shouldn’t have done it, we feel waaaaay less sympathy for this lady than if he had, say, given crappy (zing!) service… you know, rather than her ordering the pizza knowing full well she wasn’t going to tip.
In the end, he DID go back and clean it up and apologize, even after he had been fired.
