So this ^ I used to LOVE it as an employee, the guy I met on the first day told me his nick name was skippy, as he was able to get away with skipping more windows than every1 else, Its so classic to see peoples faces when they assume we are gonna come into their offices and move all their shit, in reality I walk in tell them why I'm there they normally say move what you need to to me , sorry a memo was sent out if its not already moved it will not be cleaned, to their reply oh hang on I'll move it, sorry the memo went out over a week ago and clearly stated we do not have time to wait for people to move stuff when we arrive.
then walk out of the office. WIN lol
If working in a large city you also may have to do an induction to the site, which normally wastes the 1st hour you arrive. I remember a Mobil oil refinery we had to get there at 5am for a 2 and a half hour induction after an hour and a half drive out there, SUCKED balls.
