I really know a MO guy who was taking the train Home and the train got delayed and he got off the train at shabbos, left his wallet at a laudry mat and stayed up all night. Turns out he actually was in an area with a shul but he didnt know and Shabbos morning he saw some people walking to shul and spent the rest of the day at the Rabbis house.
His wife was going crazy especially after she got a got on the answering machine from the laundry mat
