I’ve done it a number of times. One time after it hadn’t been picked up in a long time, It took, @Bill Gee, myself, and Kathy about 1:45 to count (That’s counting it twice). We now have a bill counter which helps greatly as you can count it 3 times very fast. Counter has two displays so two people can observe easily.
Takes about 30 minutes to walk around and collect it. It would help greatly if one did the walk-around and someone else did the count to reduce the time needed.
