or "go and get me a chair."?
No. I wanted him to go there and occupy a seat for me, I would be there later and sit there."Go and get me a chair." means go there, pick up a chair, and bring it back here for me." Are you sure that's what you mean?
It should be grab, not grad.Grad a seat for me.
I'd say "Save a seat for me" if I want him to keep other people from sitting in the chair that you will sit in. But I don't understand the situation. You and he need two seats (one each). Is he occupying both of them at once?No. I wanted him to go there and occupy a seat for me, I would be there later and sit there.
What can I say?
Yes, it's quite common here in China. One can not only occupy seats but tables or parking spaces if one wants to.Is he occupying both of them at once?
