Kelida,I think I mentioned this somewhere before. Nose picking works every time especially if you look uncertain as to where you intend to deposit your gleanings.
Your story brought back somw fond memories and a smile. Trust your own judgment and unless in real physical danger, don't resort to the "knee in the groin" ploy. From what I have seen of you in Mudcat, I believe you are perfectly capable of cutting down these types with a word or a glance.
You are a very special lady. If you doubt it, read the Male Postings above.
