No doubt. And it's a good business at that. All cash, who's to say how much money they make versus what they report on taxes. That extra 1 bill you offer as a "tip" is damn good money. How many of us make that per hour at our jobs? Do the math, 1 bill x 4 or 5 guys a shift, 5 days/week............. Problem comes down to what most cash businesses have (especially the ones on the "other" side of the law) is what to do with all that cash. Can't deposit large amounts without the bank reporting it. Not too many businesses take large sums of cash as payments anymore for things like cars, boats, houses, etc. The orientals are good at keeping things within the family so I'm sure that they have a way of dealing with all that cash.
