The one I used had this sign out front. I thought it was funny.
Laundromats must be a lucrative business just like lawn care. I spent about $12 to get everything washed and while I was there at least 5 other customers came in putting their clothes in a washer then leaving.
Laudromats must make for mostly passive income. I never saw the owner. If he operates a lawn care business at the same time he can check in through the day to collect money and make sure all the washers are working and not leaking.
Start a profitable lawn care business.
