Ever smell something that brings back a memory from way long ago?
I had the same sort of experience today but it was because I saw a software display screen.
I was in a popular discount store in the Southeast US today and the cashier was having some problems ringing up my order. I checked out the screen and saw a software program that I worked on 10 years ago. I used to work for a Point of Sale software company and we developed a custom POS software package for this client.
