As others have stated, get a LEO involved.. NOW. I wold not have left, the site, politely, professionally and simultaneousness on the cell phone contacted the police while ensuring the management on site understood this was not a completed action until i left WITH my property. Indirect answer to the question.. Yes I have seen it once before.. I have been near Line mechanics and shops for the last 20 years, indirectly. My wife is a service advisor, Jeep this year, previously, Chevy, Ford, and a Drive line specialty company in Alaska. As such I get to hear all the juicy tidbits the shop foremen , managers, dispatchers, service advisors, lead techs, line techs, dealership GM and owners have to spill.. For some reason the Male spouse of a female employee, who is a career US Army Soldier ,a gear head, metal fabricator, motorcycle builder , rider and racer,, is a tempting ear to bend. When silly stuff arises. the ONLY time I have seen a Box withheld, was when the employee was accused of stealing company diag tools.. and the foreman believed some of them were in his box..... but in that case the COMPANY called the LEO, and then held on to the box until they arrived (Tech had been fired that morning)
