Well, you pay for your own hotels during training, Sims, flying out of base etc.
The only time they pay for the hotel, is when you divert!
As to the "weird" expenses: Paying for an ID that you will only be using once during the base-training. Paying for your ID at all. uniform - also for tailoring new stripes on. all bus, taxi and transportation fees regarding positioning on the ground for SIMs, out of base flying etc.
As I said, you will be paying for everything yourself. Even your SIM training for OPC's LPC's and so on.
If it's not something you can accept, RYR is not for you.
You sound somewhat sceptic. I'm only trying to paint a realistic picture of RYR as a workplace for the new guys.
