| a guy goes into a work zone and waits to hear a worker's name.
 then he goes upstairs,  pretending to be a downstairs worker on
 
 a mission....and  says the guy downstairs needs to borrow a specific tool for ten minutes....
 
 the guy upstairs says:  yep ,no problem and  gives it to him....
 
 the thief   leaves the building with the tool.... later the guy upstairs
 comes down to reclaim the tool and finds out it was a scam.
