Who on earth has ever ordered just a "large pizza for pickup"? Without specifying ingredients, type of crust, anything. This is like ordering a chair by phone from a furniture store by dialing the number, saying "Armchair for pickup" and heading on over to the store. Why reserve books online from the library? Just call them and say "10 books for pickup" and then hang up.
35 minutes later, I go get the pizza.
I used to spend a lot more time giving specific ingredients, but I reached the point where it was easier to pick one or two of the 3–4 vegetarian pizzas they offer. No crust options (type _or_ thickness; it’s always thin crust).
