The 400 is great for roster but the Airbus is better for destinations and the 777 doesn't count as an SO as it is still a way off for any real variety.
So long as you don't take any of it too seriously you should be fine on the 400. Think of it as a Monty Python sketch when someone is being a pain and you can get some really good material for your later career in television comedy.
Don't lose your sense of humour like some others we see on here.
