Echoing what SN3SGuppy said, too many controllers say 'vacate next left/right' whereas I always say 'vacate next convenient left/right' so that the pilot doesn't need to brake sharply. If a particular turnoff is not available and it's the one normally used, I advise the pilot before he/she lands. Course where I am now we only have turnoffs at the runway ends, so if I see someone land and brake sharply, I advise them to 'roll to the end and vacate left/right',
