We had contracted with a large mall here in Green Bay to shuttle passengers during the Christmas shopping mess starting the day after Thanksgiving. The problem is there are too many entrances at these malls. Try to get the merchants to pay for your services. You will get tips. Some meters were well hidden and otherwise not easily found.
Bicycles are legal vehicles.
As long as the area you enter is not posted for no bicycles, you have the right mode of transportation. People are always amazed of the things we workbikers do with our vehicles. Try commuting or doing your rounds in winter. People can not believe we can ride our bikes in winter. It is actually safer than walking.
