Well seeing how this is a question that can never happen that you just created in your head, and the fact you put no rules of me being able to change or add things only that i can not(obviously) change any thing you have said, so the fact that the bank has no back doors means that the theifs have to go out of the front and since there both in the same place if i stand in front of one i do not have to worry about missing one, but since i came to go to that bathroom and my destiny is calling from inside i would call the SQR-police (super quick response) to get there instantly so i can carry on my way to the bathroom of destiny. Boom although later i regret not getting ice cream before i entered the bathroom.
