Drive-Thru Church

RE: the comcept of Drive-Thru churches...how do they handle communion? Do they have vacuum tubes like banks? Do you send up money in the tube and get a Host and a nip of wine in return?

And can you order by number at McDonald's? "I'll have the #2 extra-value salvation, with a Hail Mary on the side?" Would people be able to order super-sized confessions if they've been really really bad?
