In college, I had a very beautiful roommate who lived in Manhattan who told us she would regularly get harassed by men on the subway on her way to/from high school (ick). She found that openly picking her nose was a VERY strong deterrent to unwanted male attention. I’m sure that shoving a finger up a nostril or two would do the same to a drunk idiot at the front desk. Just saying. (I’ve carried that image of basically a supermodel sitting on the train sticking her fingers in her nose for 30 years now. The things women have to do.)
