1: Over complicate things.
Ask when trains leave York for Huddersfield. Then ask when the lasttrain will leave Kings Cross to York. Two separate questions.
Why not just ask what time they have to leave Kings Cross to make the last train for Huddersfield?
2: Tap their card in a specific way.
Seen loads of people turning their card to specifically tap it with the numbers on the bottom, as if they think it won't work with the numbers facing up.
3: Expect doors to open automatically.
Many times watched someone waiting at a door while everyone else is boarding. Once or twice the person even walks to another door.
4: Push the door open button before it's lit.
It reminds me of those people who flash at traffic lights hoping they'll change, or people who twist the little knob underneath the pedestrian button thinking it changes the lights quicker...
I had another but can't remember it right now.
1. Sometimes people can be confused and ask questions in weird ways, perhaps having mulled over the question(s) in their head then getting flustered. It's a public railway and not everyone is an expert. History shows that sometimes asking seemingly obvious questions IS a good idea when information screens can turn out to be showing incorrect information. Once bitten...
2. I can also see why some would not realise the difference between a contact less card and a paper ticket that they're probably used to having to use one specific way (face up) and, on some tickets, the right way around because the magstrip isn't centred.
3. When some trains open doors automatically and some don't, people can be confused if they live somewhere that has train doors open by themselves (like a Londoner used to the Tube).
4. On older stock this is a great trick and I bet someone who has held the button for years (not the same button!) will have been caught out by the newer stock that doesn't work that way, and requires you to take your finger off and push again once activated.
313s, 365s, 317s, 319s, 321s and many more allow this. I've also noticed that many buttons on the 313s are no longer illuminated and are unlikely to be fixed before they're replaced by 717s, so you just need to keep pressing!
Overall, nothing here is particularly weird IMHO.
People who appear to be embarrassed about knowing where the train is going:
Someone asks "Is this the train to Leeds?"
Passenger responds either "I think so" or "I hope so". Never seem to just say "Yes".
This. Although I am not sure that it's just that answering with confidence makes you look like a nerd, or the fact that people don't want to risk being wrong and blamed.
