//The non-binary passenger, who goes by the Twitter name Laurence and uses the pronouns they and them, also states they represent the Rail, Maritime and Transport trade union.//
Laurence should know that “they” and “them” are plural pronouns. They would then realise that this sounds ridiculous:
//In their complaint, Laurence stated: '"Good afternoon ladies and gentlemen, boys and girls..." so as a non binary person this announcement doesn't actually apply to me so I won't listen @LNER.'//
//London North Eastern Railway said in response to the complaint on Twitter that 'train managers should not be using language like this' before promising to take action.//
To think, they run a railway. They’d be better spending less time on Twitter and more time mending their duff Class 800 trains that have caused havoc over the last week.
