If you build a laundromat, attach a coffee shop to it, connect the two with some thick, soundproof doors, and you'll have people spending double the money. This works espeically well if you put wireless internet connections in the coffee shop, and locate it near a college campus. Keep it open 24/7, and you'll have a bunch of kids coming in to do laundry, drink coffee, and use your bandwidth to get around campus restrictions and firewalls.

A bonus is that in the winter, you can use the hot air from the dryers to heat the coffee shop, and save on heating bills.
