I'm getting sick of the SS fellow train travellers who use the wide gates because they're too lazy to get out their ticket (or they are travelling illegally without a ticket). To be clear, the wide gate is clearly marked as being for people with disabilities, the elderly, pregnant women, and people with strollers, bicycles, or suitcases. Basically anybody who can't safely get through the regular width turnstiles. The staff do attempt to enforce this, however at certain times it's really hard for them to do so without seriously impeding the flow of commuters or having an unsustainable number of staff on duty.
Back when I was a regular commuter it amused me a little, because having my ticket ready I could quite quickly get through the turnstile and on my way, while a crowd of people pushed their way through the wide gate. (Basically, due to the nature of the people who need to use the gate, it doesn't shut as fast as the normal turnstiles. What that means is if a crowd keep pushing through it won't shut for safety reasons, so they can all keep pushing through without needing a ticket). Then when I was heavily pregnant it became unsafe for me to use the regular turnstile as it would close too fast and hit my belly - one close call and I stopped. And then I discovered that having to wait and queue in a big crowd to get through the 1 big turnstile gate, just because people don't want to go through the 8 other turnstiles, really sucks.
I know all about invisible disabilities - my best friend is in her 20s, very slim and very pretty. I tell you this because nobody at a glance would ever think there was something wrong with her. But she has very complicated health issues including a rare spinal cyst that leaves her in constant pain, walks very slowly, and means climbing even 1 stair is agonising. When I'm with her I'm great at coming up with creative routes to get places! So I know a certain number of people do need the gate and we have no way of knowing which they are. However, there is no way this many people all have invisible disabilities. No way. If there were this many people with invisible disabilities in the world, we would be in serious crisis. Today my stroller was kicked (accidentally) by a guy pushing his way ahead of me through the wide gate. He was wearing a personal trainers uniform (labelled), carrying a sports bag and a sports drink, and playing with his mobile phone. A small part of me wanted to call out "Idiocy is not a disability", but of course I did not. Unfortunately my son is just too big now to carry in a baby carrier, so I have to use the stroller. I'm also annoyed when I have to wait for the elevators or can't get a seat on the entrance area of the train (there are stairs up and down to the main seating sections, but some people just prefer to sit in the entrance area because it's nearer the doors). However, those places are technically still for everybody so I get that I can't complain. It is frustrating when you've spent years leaving the special accommodations for those who need them, and when you need them temporarily yourself others don't show the same courtesy!
I work with people with disabilities and I know how frustrating this type of situation is for them. I'm of course very grateful that this is a short-term frustration for me and that most of the time I don't have to contend with this type of thing!
