I was on vacation in the US about 30 years ago. About three months before going on vacation I had been assaulted on the street in the UK with minor injury but it left me with some fears going out and I got taxis everywhere between bars if on a night out. Anyway on my US vacation I saw a pepper spray for sale quite openly in a pharmacy. I literally thought, oh great that's what I need. Ultimately I saw sense and did not purchase it.
