Hey all, I'm in the process of starting a pick-up and delivery wash and fold laundry service for the college students at my local university. My business model is as follows: 1. We issue bags to clients 2. They fill the bags with dirty clothes 3. We follow our lined out route and pick up clothes in the bag 4. Wash them and fold, put them back in bag 5. Bring them back to them Now the trouble I'm having is with the pick up and drop off. I'm trying to think of a way they can leave their bags outside, so they won't have to be there waiting on me, without them getting stolen. Then I can drop them off in the same fashion, without them getting stolen. I've thought of issuing some sort of lock with the bags, but the strings on the bag could easily be cut off. Any ideas?
