The New York City Subway Said That Dogs Only Allowed to Ride in Bags
Dogs are not allowed to ride the tube in New York City unless they can fit inside a bag, as everyone in the city is aware. However, the man had a large dog that would not fit inside a typical-sized bag. By locating the largest one and placing his dog inside, he was able to circumvent the regulations and the dog appeared to be relieved to be able to ride the tube once more.
Since that is a bag and the dog appeared to fit inside, we don’t see how any rules were breached in this situation. If it was an enormous IKEA bag, so what?
