Zach is Newman from Seinfeld
Zach, the delivery man who gives Enrico a lift, is played by Wayne Knight, who of course played Newman, a postal worker, on the sitcom Seinfeld. Perhaps they're actually the same character? It helps that in Seinfeld, we never know if Newman was a first and last name (although it was hinted a couple times that it's his last name). Perhaps his first name happened to be Zach?
