Reply To: Tznius — Not Directly Handing Items Between Men and Women

“I have known people who seek to casually have such encounters that appear to be fully innocent, but, at least to that individual, are not”
With all respect, not many frum yidden (or even goyim for that matter) go to Costco hoping for an “inappropriate” finger touch with the cashier or an arm touch with the guy helping you load 2x4s at Home Depot. If you are talking about someone with some “emotional” or “mental health” problems deliberately seeking to make an inappropriate physical contact in the context of some normal social or commercial interaction than I guess the OP didn’t make that clear. Obviously, the latter could be a matter of negiah or tzinius (as well as violation of secular criminal law if the touching goes beyond a certain level).
