I really don't see why more laundromats haven't added cafés and internet/wifi, or even small eateries. Or conversely, some cafés haven't added small laundromats.
I work a single day at a laundromat/bar combination to supplement my income and actually be on my feet for a day. Most people are amazed it isn't more popular when they discover it. Having a cold draft while waiting for your wash or folding your clothes can be quite nice. We even have regulars who just drink.
We are near a university, so I think this works out better than say a rural or low-income area. We have a large homeless population around here who use the establishment, and can be a bit bothersome in some of their behavior when visiting (such as whore bath in the bathroom).
The laundromat I used in grad school was owned by Korean immigrants. They opened up a little restaurant that became popular enough that when I went in to do laundry one day during the summer they told me they weren't running the laundromat during the summer.

We have free WiFi as well.
