Could you pass me the salt? or Could you pass the salt? [closed]
Solution 1:
I think there are two questions there - "which is more common?" and "what is the difference?"
In terms of "which is the more common?", that will depend very much on what circles you move in. I am sure if you eavesdropped in many restaurants and cafés around the country you will find a wide variety not just of those two, but many other forms as well.
What is the difference? There is a general acceptance that in the absence of the subject, it is implied as one of: the speaker (me); the place of the speaker (here); the time of the speaker (now). It depends on the context as to which one of those is applicable.
