I bet ED has the same 'run' speed as the movie trilogy Murphy and the horizontal booster is a separate attachment from the stair booster. That being said, I would think that a freestanding ATM unit would be considered automatically suspicious in this day and age. Lots of room for a RFID scanner or other shenanigans on the back or bottom of the unit.

I'm not sure whether it was intentional or if my sanity has finally left me, but ATM's look disturbingly like an imposter.

a mimic that imitates into an atm machine sounds more horrifying than a regular chest

Considering the kind of stories I've read of ATM robberies, these girls are taking their lives into their hands...

Are mimics so good at mimicry that they can deceive even other mimics? Or does just this particular one lack awareness?

If nothing else, their slime doesn't seem to effect one another.

Probably the latter, she doesn't even know what the 'N' in PIN stands for.
