Beer for baggage-attendant (6)
I believe the answer is:
porter
'beer' is the definition.
(type of beer)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for porter that I've seen before include "Stout" , "Doorkeeper; dark beer" , "Railway worker; the Ruler of the Queen's Navee (G&S)" , "Dark beer; carrier" , "He should be able to carry" .)
