Suppose I'm at a bank and all the service counters are numbered. How can you say something like:
Please come to counter number 2.
If all the counters were active and numbered in order then I guess I could say:
Is this natural?
But if counter number 2 is closed then the second counter would be counter number 3. So how can I refer to the counter by it's labelled number rather than it's position in a sequence.
