don't forget a few wired connections too for the poor schmucks who don't have wifi cards. I'd probably eventually put some PC's in there - let the people who don't have laptops surf - for a fee of course. You could even do a "cup of coffee gets you 15 minutes" deal.
If you don't wanna do a coffee shop, you can put a couple of video games, a drink, and a snack machine in your laundromat. People get bored and hungry when they're just sitting and watching clothes spin. Easy money maker.
Here's a trick I've seen a few laundromats do. They buy washing machines that have no spin cycle. Then they put a clothes spinner in there and make it cost a dollar. So you have to pay for the wash, then pay for the spinner before you pay for the dryer - if you don't do the middle step your clothes are soaked and take at least 4 cycles to dry. Guaranteed money maker, but this trick will only work if you don't have any other laundromats with normal washing machines anywhere nearby. Hell of it is, most people don't even glance at the clothes spinner until the washing machine stops and their clothes have tons of water in them still. Then they see the sign
