People Watching

So I was sitting in the parking lot of CVS for about a half hour tonight waiting for my prescriptions to be filled.  Watching people come out of a pharmacy is really interesting.  One guy I saw walked out carrying only an ice cream bar.  Who would think to go to CVS just to buy an ice cream bar?  Then another guy came out carrying just a thing of dental floss.  He subsequently opened the package in the parking lot and started flossing his teeth as he walked to his car.  Weird.
