"Place a bold price list for all to see"

This one little thing will be a major improvement for all businesses. I myself do not like walking in "blind" to the cost of things; more time I will observe for a bit and get a feel for what the place is charging. A. to make sure I can afford it and B. to make sure there is no discrepancy in pricing due to one's complexion or perceived "status".

As a veteran worker in the service industry I keep an eye on quality of service, cleanliness and yes a decent restroom is a must!
