Lol, atleast charge a nominal fee, it's way more suspicious for a pizza place to just give away pizza. Like ask for 10 bucks and get a pack of smokes for you and Jimmy No Ears.
IN my city there was a case in which cops did watch a joint for a couple of days multiple days per week. They noticed that the amount of real customers was much much lower than the earnings reported. So they took quite a bit of money and had that money laundering charge.
