OBS Chief
There is a business class attendant who will give you your voucher, the WiFi password and, usually, a bottle of water and a pillow right after you board. After that, it depends. Some will disappear until the next stop, others will more or less always be around and offer you more water and see if you need anything else. Including, in one case, access to the PPC for drinks. Some get tips, some don't.
You'll hear all the announcements.
