Pizza places make great fronts for distributing money in general and dealing drugs in particular. Pre-pandemic, pizza was a cash-heavy business with plausible reasons for making late-night on-demand deliveries to homes and hotels, and a business culture which suits this purpose.

Think of all the ways you can customize a pizza order, all the things a pizza place can plausibly put on the menu without raising suspicion, and all the things you can communicate at the intersection between the two. (What's that? Someone actually wants a smoked meat platter with double onion rings, a side of ranch, two bottles of Fresca, a cheddar habanero sauce, and a pack of pretzel brownies? Sorry, we're all out of smoked meat, and onion rings, and Fresca... yeah, it's the supply chain stuff, it's all been backed up since Covid, you know how it is)

And low-end pizza delivery exists at an interesting financial intersection: it's a very cost-competitive industry (if you're charging $5 more than Pizza Pizza per pie, you won't attract any business), but it still has room for caprice. Why do all my regular customers keep ordering from me despite the fact that I charge so much more than all my competition? Oh, I guess it's just the way I make the pizza: you know how people are, they find something that scratches the itch, and they order it again and again. And if some of them are generous cash-only tippers, that's their business.
