Some SCAs can be rigid in wanting to do things, such as making up berths, on their own schedule, not at the passengers convienence. It is against policy and is one of my "no tip" red lines. Not so much for room service meals, though, I understand SCAs wanting to consolidate those so as to minimize running back and forth to the diner throughout meal service. It doesn't come up for me often, though. I've only done a room service meal once in many, many miles and days on board, when I was not feeling well.
On the other hand some passengers can be jerks, too.
Personally, I usually try not to get into it with crew members at all onboard, no matter how poor the service may be. It just makes the trip even less pleasant than the poor service alone would make it. If really bad, I'll withhold a tip entirely, and may call Customer Relations. Once an attendant displayed such a bad attitude I called Customer Relations while still onboard. However, I never threaten to call Customer Relations, I just do it. The object of my complaint never hears a word about it from me.
My advice for
@Just-Thinking-51 from this point is to eat in the diner/cafe, let the SCA put the berth down when they want to, don't tip when you detrain, and maybe call Customer Relations. Do not engage the SCA any more than you have to.
And no, the SCA does not have the authority to kick you out of your room. The conductor does. They may decide to move you to another car if space is available to keep the peace, but won't downgrade you. They might kick you off, though, if they consider you unmanageable. Never get the least little bit hostile with a conductor, that is a fight you are guaranteed not to win.
