Twice in the last 3 days I have got on the bus and all pairs of seats have one person on them. Both times I see the person who has their bag on the seat next to them so politely say excuse me and ask them to move their bag so I can sit next to them. Both times they look around at all the other empty aisle seats wondering why I didn’t just sit on one of them. It’s because you are a selfish twit (edited to change vowel in last word due to falling foul or the swear filter, sorry mods)
