I finally pulled the trigger and got rid of the trash cans at my two car washes. Best thing I ever did. I get a little bit of people just throwing trash on the ground but very little. No more POS minivans that pull up and block the entrance to the bays for 40 minutes at a time just dumping trash and not spending a dime. No more filling the entire can and spend $1 on a vacuum. Its seems a little weird when they dump the dumpster there is 1' of trash in the bottom of it. This is becoming a trend in my area. I know of 2 other washes in neighboring towns that have also pulled their trash cans with similar results.
