All the pizza joints in my area survived on pickup & delivery. IOW, the normal pizza business model.
It’s the normal model now, but in the 80s and early 90s it wasn’t. There’s still some people that think it’s a viable model (to the point where they don’t offer delivery in their pizza shops and may not even offer carryout) but it was not so slowly dying before COVID-19. With COVID-19? They’re doomed.
