I actually kind of applaud this guy. At least he's trying to be proactive about not being a burden or problem to another new-hire that's forced to share a room with him. That's a lot more than can be said for a lot of people who have a snoring problem that DGAF about the other people affected around them.
I know what it's like to share a room with a loud snorer during training. It's absolute torture. Besides, isn't it a bit insane that airlines are still forcing grown, adult professionals to share a bedroom during training? For *******'s sake this isn't freshman year in college.
