What may be the reason?
How entitled do you have to be to take not one, not two, but three whole seats on a Subway? And this has been going on for some time before someone took a snap of it, and everyone in the sub was too terrified to find out what’s resting behind the umbrella to tell anything.
Being a time traveler from 1800, with no public transport etiquette can be the only plausible reason for this kind of behavior!
