The whole dining car just sounds like too much of a pain in the rear.
I have so much anxiety from reading all this, standing in the dining car, LSA's running around barking at diners, going for your reservation at 6pm only to wait in the lounge car for an hour waiting for your table. (why would I want to sit in the lounge car for an hour, when I can be in my room, watching my belongings, and relaxing. )
It sounds like I am either going to get an SCA who will allow me to take my meals in my room, or I will be SOL for food for 2 days.
Between having to pack up my laptop, ipad, and other valuables and hauling them to the diner, dealing with a swamp of people.
Sorry but I make small talk, with customers for a living 16 hours a day 7 days a week. When I am on vacation, I want to enjoy my peace, and the view from the window. If I wanted to socialize and deal with crowds, I would go to a singles resort.
I guess if I get a surly SCA, and a word with the conductor will not remedy the situation, I will just go 2 days without food, and will be demanding a refund of a majority of my sleeper costs.
Edit, add - Because this whole dining room fiasco just sounds like a personal panic attack waiting to happen.
You are only hearing about a few incidents. I personally have not had any problems with the diner situation. Granted I've only been on 3 LD trains.
It's the same with flying. Some people will refuse to fly because of 1 crash. How many planes are taking off and landing in one day, heck, in one hour, but because 1 plane crashed, these people refuse to fly.
If your SCA doesn't bring your meal to your room (and I have no problem with you eating in your room), then at least try the diner once. If you have a bad experience, then avoid it the rest of the trip if you want.
Also, remember, when people post, they're posting from their viewpoint of the situcaton which could be very different from another's viewpoint.
