>"people under 60 that uses cash are considered, if not criminal, at least suspicious, like they have something to hide. Or simply wackos."
I have barely used cash in 25 years. This doesn't mean anything at all. You're probably putting this solely in the context of using cash for significantly large purchases, e.g. higher 4 digit sum or above, or as in your example a craftsman who want to exempt it from his or her accounting. Nobody bats an eye at a person buying groceries, or some gadget for a couple of hundred, with cash.
