I've had a number of minor bad experiences. none bad enough to make the papers. i do feel bad for the staff.
mostly i notice that things that were always straightforward - checking in, breakfast, hot water, towels or soap or whatever - now are just hit and miss. sometimes it's done one way, sometimes another. sometimes there is a pencil for the menu, sometimes i've gotten someone else's leftover toiletries...none serious, but indicative of chaos behind the scenes?
Bright lights coming on randomly in the night is probably the most annoying thing, and which has now happened to me several times.
The worst single experience that I've had was whenapparently the mirror on the door of my berth had broken, and made the room unusable. so they didn't have a room for me until carstairs, when the glasgow carriages were added and told me to sit in the lounge. it didn't help that I was tired and just wanted to lie down. eventually i asked for some water to take a headache pill. at which point it occurred to them that they could actually have offered me a drink etc. by the time they found me a (non-ensuite) berth, i was so tired that when i tried to use the loo i couldn't work out how to lock it. i thought it was broken. only realised next trip that I had clearly just been incoherent with exhaustion. it would have all been better if when i 'checked in' they hadn't said 'But you're supposed to be joining us in Glasgow'. as if they had let me know?
