I started using them in 1979 (sic), Diebolds used by BayBank, a Boston area consumer oriented bank, and in the early-mid 80s had a couple of failures to dispense altogether. The first time it was right at a bank branch, so they extracted it from the machine. 2nd time was at a random mall location and after hours, and I wondered if asking for one more $20 would kick out the ones already dispensed, which it did. To this day I count all the bills ^_^.
