Gibraltar's emergency services never close. The Royal Gibraltar Police, the Gibraltar Defence Police, Gibraltar Fire and Rescue Service, the GHA's ambulance crews, HM Customs and the Borders and Coastguard Agency all have people on duty through the night, at weekends and on bank holidays.
Crews eat when they can rather than when they'd like to. A machine on station means a drink and a snack are waiting when they get back from a call, at 4pm or 4am.
Card-only machines also suit secure buildings: there's no cash on site and nothing for your staff to look after.
