Okay then, the designer of that workplace attached to the ATM. They need to have contingency plans built in.
For instance, I think most trunks in our cars have a button or lever you can push to open from the inside.
I also believe there should be an ‘SOS’ key for customers who are being robbed/ordered to get cash from their ATM by force. Thieves know how to fool the cameras.
People use ATM machines at their peril - they need a button (or a gun).
It is very difficult to make something completely idiot proof. Some idiots are very resourceful.
Also, everyone makes mistakes - you & me included.
Give the repairman and the designers a pass and a thank you for the good laugh.
