Smoking? You shouldn’t have a pen (5)

Ross

I believe the answer is:

tasty

'smoking?' is the definition.
(both can mean attractive)

'you shouldn't have a pen' is the wordplay.
'you shouldn't have' becomes 'ta' (both can mean 'thank you').
'a pen' becomes 'sty' (sty is a kind of pen).
'ta'+'sty'='TASTY'

(Other definitions for tasty that I've seen before include "Savoury" , "Delicious" , "Pleasant to savour" , "Sexually attractive?" , "Palatable" .)

I've seen this clue in The Sunday Times.
