The rules posted on the computer say that it should only be used fifteen minutes in any one hour. A good rule as this is a heavily used machine. There is no chair, you have to stand. The CO-OP is open from 8 AM to 10 PM every day, so this is one to use when most of the others are closed. The co-op is doing this because they are great people, but I think that big stores like this can make a profit off this.
People come in check their mail and buy food.
Other grocery stores should study this. Also drug stores, department stores, and hardware stores. Note if you have a small specialty store people will usually just refuse to use your machine. You need to be selling goods that are needed by most people and are bought frequently to have a popular computer that will draw people in. At the city hall in the parks and recreation department there is a pretty good computer.
