Decline drink (4)

Ross

I believe the answer is:

sink

I believe this is a double definition.

'decline' is the first definition.
(I know that sink is a more specific form of drop)

'drink' is the second definition.
(I've seen this before)

(Other definitions for sink that I've seen before include "Get worse" , "Plunge down" , "place of iniquity?" , "drink" , "Plumbing fixture" .)

I've seen this clue in The Times.
