It's just your own (lack of) luck.
Seriously, don't they offer multiple machine locations up there? All my bank's locations have
at least 2 ATMs, some more.
It also sounds like you're suffering from "over politeness syndrome". It's a common illness among us guys brought up to quietly and patiently wait in queue without a murmur of protest. It was once considered the sign of a gentleman. These days it marks us as suckers.
Next time, lean up and ask, "If you need some time, could I go first? I only need a few seconds then you can stand here and dither around all day if you like." Feel free to mention your terminal illness that will kill you within 5 days and the fact you'd like to enjoy your remaining few days on Earth with your family, not waiting in line behind her.
