oh boy...I have a new one.
for reasons that are beyond the scope, I found myself lugging two roll-aboards and a backpack through a US subway system today. Instead of clogging up the escalator as I exited the station I decided to drag them up the stairs (for my health...yeah...thats why)
About two thirds of the way up, my right hand goes light and I turn around to realize that my bag is tumbling down the stairs while I have been left merely holding the handle of the bag. It didn't hit anyone but I looked like a complete dumba** I am sure. Had the wonderful walk of shame down the stairs to retrieve my bad and then drag it (by the support shaft) back up the stairs, out of the station and into my hotel.
