The automated text told me he was at my location, but I didn't see him. After a very brief, highly windy phone call with some back and forth, we managed to spot each other (maybe I should have told him I was very, very, very good looking?).
The exchange was no different than if I met the delivery person at my front door. I was also the first "hot spot" customer this particular driver had, and I was very happy to pop this cherry. The driver confirmed that this was an easy, seemingly simple way to deliver pizza, and he was pleased that this initial run went so smoothly.
After that, I frolicked in the park for a little bit, tossing around the ol' pigskin, handing out pizza to strangers, and generally enjoying my newfound pie-based liberation.
