I’ve done a lot of odd jobs over the years in between “real” jobs. One was demo’ing software in the big box stores. Once at Costco, I had to inflate Quicken balloons for my display. I should put it on my résumé.
(It didn’t end well. A little boy kept sneaking behind the booth to try to play with the helium. I sternly banished him. Later, his dad came to the display to yell at me. I actually thought he had come to apologize for his son’s behavior. My blood still boils a bit remembering that jerk!)
