Now, this is interesting.

I've always interpreted 'No Soliciting' signs as "Please don't try to sell me. I can't say, 'No.'"

Frank raises interesting questions.

Do you want to be approached by salespeople as you're heading into a restaurant, store, gas station, or any other place of business? (I'm reminded of being on a Caribbean beach, street, or parking lot and being asked to buy timeshares or my wife to get her hair braided.)

Does the owner get to pick who does business on his property? How about the Chevy guy that hands out business cards or coupons to prospects roaming the Ford lot?

I also put this question on LinkedIn. There's lots of places for you to comment.
