We use dry cleaners quite a bit so here is the customers side.
We will only deal with cleaners that keep clothes on site. The place that seems to always be super busy is the $1.95 each for anything, cash only in advance, in by 9 out by 4. That's where we go and they even have coupons, can't beat em.
Personally, I would not consider a business that was so labor intensive that I could not move off shore. It's getting too expensive to have employees anymore, not to mention they tend to steal from you. Also, think of a business that you do not have to be there to always unlock a door to make money, I went for years without a vacation because of that, never again.
