You'll need a bloody good sense of humour I can tell you.
Why? Because when crewing forget to book you a hotel or taxi and you are standing around waiting to get into your "room" or a taxi so you can go home you can remember just why you started this game.
Don't think I am joking? Ha! I am not. Perhaps it is better in the SLF world but in the freight world you are just another money making cog in the wheel.
Oh I forgot, crewing will also forget to book you a flight home. (When positioning).
Min rest. I love it.
