My ATMS never run out, they print up as much Fiat as they need herein America :D
But in all seriousness, we RARELY have ATMS run out of Cash here, sometimes the will say out of order and its a trick to not Panic people and alert them that the ATMis actually OUT of cash, so they say out of ordr and a guy comes to refill it ive seen a guy refill a cannabis dispensary TM with Cash and he jst came in with a backpack and refilled an TM with cash inspired me to want to own oney Machine

But yeah if there IS a time whe thereis no mro cashleft its great! Tmeansi will be able to use my Crypt s it was intended, without the ned to cash out , and it will work great!
