Works hard to get good service at empty tearooms (6)

Ross

I believe the answer is:

grafts

Here is my best explanation:

'works hard' is the definition.
(I've seen this before)

'good service at empty tearooms' is the wordplay.
'good' becomes 'g' (abbreviation).
'service' becomes 'raf' (**).
'at' means one lot of letters go next to another.
'empty' means to remove the middle letters.
'tearooms' with its middle taken out is 'ts'.
'g'+'raf'+'ts'='GRAFTS'

'to get' is the link.
