Vacuum entitlement?

I understand what happens when a vacuum motor quits working and you do not notice; someone will pull the hose off the machine.  Sometimes they will steal the vacuum nozzle, other times they steal the whole hose and nozzle.  This guy stole the whole thing because the shampooer was out?  What?  After stealing the hose he went to another shampooer to shampoo his truck.  (Disclaimer:  I actually do not understand why people do  this act.  I just think I understand the warped logic.)
