Do any of them using Twitter as their only method though?
The way I've seen it used is that it is usually given as option to give quicker responses than what the regular customer services team would be able to give, but it doesn't replace the other ways of contacting that customer services team (which is usually via email, phone or by a contact form on the website).
Twitter is a great way of communicating to lots of people at once with information that is relevant to large numbers of people - one tweet can reach thousands of people, rather than sending an equivalent number of emails or handling that number of telephone calls - I can see why companies find it much easier/ better than other means of communication
That's not to say it should be the only method, but I don't think it is ever the only method (just that some companies try to encourage people to go down that route as a first preference)
The problem with public transport enquiries on Twitter is more to do with the wait that companies have centralised teams to deal with enquiries (which means that they can't help as easily with questions about diversions, they just have a standard script) and the kind of people who jump in on conversations to give your their opinion of things, giving out what they think is helpful information but can be a problem since the company isn't going to honour any decision made because some stranger barged into an enquiry (whereas, if you did make a decision based on a company's Twitter account then you'd have grounds for compensation if things didn't pan out)
Referring to anyone objectionable or abusive on social media as a troll. Trolls are completely different: they seek to stir up discord on social media by the timely voicing of (faked) controversial views.
Incorrect use of the term staycation, which means a holiday enjoyed from one's home, not going away in the UK. But it shouldn't' really be used in either sense.
Agreed on both points - "trolling" is an art form sometimes, the way that people carefully distract/ disingenuously move the conversation on/ bring up some irrelevant details... rather than the pretty blunt abuse that some people go in for on social media (yet get called "trolls")
I don't like the word "staycation" either, but surely if it means anything it means "days out from home" - including every holiday that doesn't require a passport is daft (and pretty insulting to people who can't afford continental travel each year)
People who arrange their books by the colour of the spine.
Do people actually do that?!
A depressing number of people seem to, if Zoom is anything to go by - bookcases become a colour co-ordinated fashion statement rather than a practical library (where you store similar books together so that you can find them easily)
