Add to the list almost all high end (dance) clubs, the kind that sell you the $50 bottle of champagne for $5000, "cleaning" thousands for every easily justifiable and anonymous bottle sale with close to 0 effort.
Actually, any business that can just add an arbitrarily huge markup for what are otherwise cheap, run of the mill products and services is probably also laundering money. Usually exclusive/luxury places, the ones where in one go they can convert the lowest possible cost into the highest possible clean profit.
