I hope it hasn't, but if you have ever tried transporting long window coverings in an elevator this video might make you laugh or it could trigger a post traumatic stress response. Either way, you should watch as a reminder of what NOT to do.
Off camera he is actually sticking one end of the pipes out through a ceiling tile into the elevator shaft. Wait or skip ahead to about 1:20 in the video to see what happens.
Has this ever happened to you?
