Sorry Lobe but the shower attendants only do that. They stand at the top of the front stairs the whole time (or sit on them), can't see anything except the steep stairs and are bored as bat5hit for much of a long hop. Often only one will be on deck, the other having a kip.
They are in a different uniform to the F/As and do not do any F/A duties. They don't even re-stock the drinks in the P/C 'social area' at the top of the stairs. They just make sure the shower/loo rooms are tickety-boo after every visit by a punter. So the bog-rolls are always perfect, the showers dried, the amenities re-stocked and presented, etc. after every punter visit or turbulence event.
