I felt so awkward a watching this. A woman's perspective here! "Personal Space". Heard of that? I've always been told/taught that if you need to be in physical contact with another person, you must always demo on yourself first while explaining what you will be doing. Personal space is a hidden rule, never invade it, a shake of the hands is enough to introduce yourself. Then go ahead and use yourself to explain where the mic and pack will be placed. If I had a stranger approach me with a whole hand coming at my chest like that, I'd probably kick up a fuss way before he had a chance to trace his hand down my body and hip.
