There are many wonderful things about living in HK, but this is not one of them. When I was pregnant, my blood used to boil watching able bodied young people fix their eyes determinedly on their phones in the MTR or pretend to sleep so as to avoid giving up their seats. I would stand there, sometimes in front of the happy sticker urging people to give their seat to someone in need, pleadingly staring. Sometimes someone would notice and get up, and often it was an older person. There have been times when elderly people would get up for me and I'd insist they sit back down. There have also been times when I, pregnant, would give up my seat to an elderly person with a stick because I could not bear to see them jerking around in the train. It never occurred to the young people to get up, even when they saw this happen.
My husband suggested I just request someone to give me a seat but I never felt comfortable doing that. Well, except when my baby was a month old and I needed to take her to a doctor in Central. A couple of times I requested someone for a seat and they were nice about it though I always had to ask. In a very crowded train, once an elderly man gave me his seat willingly. The last time, though, I was in for a shock when I requested a young lady for her seat as I was carrying my baby. She got up and then after a moment told me off for being rude and asking her when I should have waited for someone to offer. I pointed out that in my experience during pregnancy noone would offer and her response was she had also been pregnant and noone offered (apparently she thought this was the right way for things to be). She also said she was doing something and showed me her phone (I had not interrupted her talking on the phone, she was merely playing with it as everyone seems to do in the MTR, nothing that could not be done standing) and then asked "why me?" as if I had targeted her for some henious activity. I was gobsmacked especially when it turned out she was getting out at Causeway Bay, meaning she only had to give up her seat for a couple of stops. It really left me with a bad taste in my mouth, because it was the culmination of so many experiences of selfishness out and about in HK such as people pushing past me for a seat when I was pregnant during peak hours in the MTR, able-bodied people crowding into the elevator when there are elderly people and those with strollers waiting.
Like someone else said, I do try to focus on the kind souls that are helpful and considerate but they are really few and far between. There is something wrong at the heart of the society and it's not just me or expats who notice this. My Chinese colleagues asked me if people offered me a seat when I was pregnant and when I said no, they were not surprised. I work for a university and one of the things being discussed is how to imbibe these values in young people since they seem to have not learnt them thus far.
Also, as someone above said, we have to be watchful that we don't become the same ourselves. I restrain myself from reaching for the "door close" button these days. I make a conscious effort to be alert in the MTR to people who might be in need, and to offer my seat even if they might turn me down. I smile if people make eye contact with me.
