I stop after short time — somewhere to get a little drink? (7)
I believe the answer is:
minibar
'somewhere to get a little drink?' is the definition.
(a minibar is a small container for drinks)
'i stop after short time' is the wordplay.
'stop' becomes 'bar' (bar can mean to stop or prevent).
'after' is a charade indicator (letters next to each other).
'short time' becomes 'min' (short for minute; 'short' suggests a short form).
'i'+'bar'='ibar'
'ibar' put after 'min' is 'MINIBAR'.
(Other definitions for minibar that I've seen before include "Hotel room chiller?" , "Temptation in hotel room" , "cooler for hotel guest?" , "Source of hotel room drinks" , "Hotel room fridge" .)
