I was working as a contractor for 511 (aka MTA Customer Service) on nights and weekends. Sunday nights were the best, the level of phone calls dropped dramatically, so there was actually some down time to enjoy. I didn’t particularly care for this job, management had created such a toxic work environment long before I arrived on their doorstep. I had dropped my NYC subway map on the floor and stomped on it - thus inspiration struck and in idea was born!
