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:
- Park the vehicle to block both lanes.
- Open up both machines.
- Have both people service the first machine, but don't put it back in service yet.
- Have both people service the second machine.
- Just before finishing the second machine, have one person restart the first machine so both restart at the same time.
- 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!
