YANBU.
In Singapore people on the tube system suddenly developed narcolepsy when I was heavily pregnant and got on. Right in the middle of crosswords, texting, reading the paper. They all mysteriously fell asleep.
There's also a thing called 'choping', or reserving a seat with a packet of tissues or paper. Waiting for the train to pull into the station I could feel this guy elbowing me. As the doors opened and we could see someone in the priority seat get up, he tried to squeeze past to get it but couldn't, so he threw his newspaper above my head to 'chope' the seat.
Needless to say I was so shocked, and so hormonal that I couldn't say anything (didn't want to lose my cool). But I cried once I got to my station. I felt that big.
