Okay, so you needed to vent.
And your specific complaints are:
(1) They didn't make all requests in a nice enough manner,
(2) They didn't provide you with your own personal thermostat, which as we know is standard on all other means of travel, and
(3) When you missed your train through your own fault, they gave you full credit for future travel (and in fact would have even given you cash back minus 10% if you had asked). Despite that in general airlines would never let you do this with an advance purchase ticket, you remain upset that they didn't also offer to reschedule you on the next train for free.
It sounds like an absolutely horrible trip.
