This is a very funny Tumblr. I admittedly do this sometimes on the train, when seats are not full. Because I feel a little bad in these situations–but not bad enough to move my bag off the seat next to me–I will when people come on board make a gesture of getting ready to move my bag.
Guesses as to what city this is? I think maybe in the UK (but not London?) or Canada.
