One or 2 years ago, the machine 'hesitated' while it was dispensing the cash. I was concerned but not able to examine the money right then. When I counted it out in my room I found an extra $200 jmd in the midst of 1,000 bills ... the machine must have recognized the wrong bills, and corrected itself.

Tip: come with 2 ATM Debit cards, so you have a backup if any problem.
