Spent the better part of an hour today trouble shooting one at a branch I had previously never visited. I had to - my zincs were only half counted when the thing jammed. I told the teller I might be able to fix it and she, one of only two people working at the branch, was only to happy to oblige. They sure are trusting folk

I was knee deep in quarter bags and penny heaven. Course, there were probably 47 cameras on me the whole while...Eventually I managed to unjam it (a technical term). Someone had dropped one of those elongated Lincolns into it which not only froze the wheel-thingie (again, technical), but also pushed the sensor aside.
Next time I'll bring my 15 in 1 pocket utility tool. That will impress them.
