Pretty simple, that pizza would have sat on the counter. I would have refused to accept. If they provide service above and beyond, I'll tip. If they just do the ordinary, I'm not going to! It's not like their prices are cheap. $19 for a cheese pizza is just as likely to get my business as $24 so they'd do better to just price it up front.

Too many choices, especially for good pizza in the district to accept that.
