I don't think it means the machine was tampered with. It has been my experience that some machines have a narrower dispenser for withdrawals, for sure the one at Sunshine Plaza. That one can reasonably handle 22,000. If you want some small bills, the max to request would be 13,900. The one inside NCB bank can handle more, I think at 27K I didn't have to tug it out. The Sagicor ATM next to the Cambio in in town may be able to handle 30 or 28.
