I rarely use ATMs for the reasons described. I am almost always armed ("always" is close, but potentially inaccurate), and I would not have used that ATM either. If I had my dog with me AND REALLY NEEDED the cash*, I MIGHT, especially when I had Bozo (and I would taken off his muzzle just to communicate the reason for him being with me) ... but if it does not look right it probably isn't and you should surely act that way.

*I rarely need cash, and try like heck to avoid carrying much. If I am sure I will need it, I try to plan in advance so I don't have to go the ATM or similar setting.
