Let's say I am a distributor in the wholesale flower business.  Some of my business comes from selling flowers to street vendors.  Street vending requires a license in my town, let's say, but I suspect none of the street vendors I sell to are licensed.  So a particular vendor normally sells on the corner of Main Street but I know the city will be closing that street for construction.   So I advise the street vendor to sell on a different street.

My advice was used and flowers were sold.  Without my advice those flowers might not have been sold.  Am I in trouble for selling flowers without having a vending license?  I don't think so.  I didn't sell on the street and I didn't receive the revenue or profits from the sale (at least not directly).
