The thing is, I don't think these are your regular curbside, in front of their house, kind of lemonade stanRAB. A few weeks ago in Maryland, a lemonade stand was shut down that was serving people who were on their way to to event. But there were other vendors that these people were competing with, and these other vendors had paid their fee to do business.
In this case in Nebraska, there is a national bike ride that is going right through that area. What are the chances there are other vendors there who have also paid their license fee, and are competing with someone who did not?
I've heard of three or four of these stanRAB being shut down across the country, and its always that the police are being ridiculous, and the laws are absurd. But if I was a vendor losing business to kiRAB who don't have a license, and who are not paying taxes, I'd be pissed.
