It stopped a little while before the new stock came in. I shared in my twenties and didn't think anything of it then, but by the time i resumed trips on the sleeper in my mid fifties i was no longer interested in sharing with a stranger. The options then were to book it and hope that there would be enough capacity that you wouldn't have to share or pay extra for single occupancy. They called this 'First Class'. It was exactly the same room but for the additional money you got use of the lounges at the termini, a better breakfast and access to the lounge car, although i dont recall anyone ever challenging me on my ticket class for this.
In the olden days when female staff were still a rarity, I recall a civil service friend of mine was always first pick as "bag-carrier" when any of her superiors had a trip to Scotland because, unlike the male junior staff, she wouldn't be expected to share a cabin with the senior officer she was travelling with, so they would both have to go First Class. As she was Scottish, she also got a free trip to see her family.
I wonder how busy the first services after the strike tomorrow night will be?
Difficult to say. Most people, like me, will have taken their refund (processed very efficiently and without any input required from me*) and made alternative travel arrangements. The service is generally popular on Sunday nights, so it was probably close to being fully booked long before the strike was called.
(*unlike Thello, who have still not refunded me for a cancelled booking last July)
That strike has cost four days of my life. Firstly, we had to set off for Scotland 18 hours earlier than intended, to fly up to Glasgow and then get a local train to Fort William and spend the night in a hotel there. Presumably somewhere on the plane or in the hotel (at a time when I hadn't intended to be in Scotland in the first place) I must had contact with someone with the Lurgi, as Scottish Track & Trace texted me and required me to quarantine in a hotel room in the remote Highlands for several days, postponing my return home (also by plane rather than train) by a further three days. (I have since had a negative PCR test, by the way)
