If my wash was in Chicago where there's an endless supply of potential customers, that'd be one thing. But here in a small town in the south it would be a net negative for sure. Probably a big one. And it might foster the wrong sort hanging out at my wash.
Not to equate the two, but I agree you have to draw a line somewhere beyond what is merely profitable. If not, why not vend vibrators and blow up dolls? And why stop there, French Ticklers would probably sell better than
Armor All so why not ditch the
Armor All and go with a complete line-up of sex aids? Because it's a car wash, that's why. There's probably a Walgreens and an adult book store nearby for the other stuff.
But hey, that's the beauty of America; everyone gets to run their wash any way they want. It's like I've been known to tell the jerk who chews me out because I won't allow him to blast nails out of his pickup bed all over the place:
Sir, in this country when a guy ponies up his own money to build a business he gets to run it how he sees fit - if I want to put a sign out front that says I only allow customers who're wearing purple pants, either go get yourself some purple pant, or go elsewhere.
