   This morning (on my bicycle) I swing by a branch of my bank that has
   two adjoining drive-through ATM's. An armored vehicle is there, with
   two people, just starting the daily unload/reload. I have to wait
   nearly 15 minutes because they take them both down at once.
   The process is:
    1. Park the vehicle to block both lanes.
    2. Open up both machines.
    3. Have both people service the first machine, but don't put it back
       in service yet.
    4. Have both people service the second machine.
    5. Just before finishing the second machine, have one person restart
       the first machine so both restart at the same time.
    6. Pack up, leave.

   The technicians were polite and worked quickly but gained no
   significant time versus doing one at a time. I can see that having
   them work in pairs is a good security measure, each watching the other
   and the tens of thousands of dollars involved.
   But one at a time, please!
