Communication with the buyers

Hi everyone, I just want to ask for some tips on how to deal with a certain situation wherein the buyer doesn't talk in complete sentences or in broken english, and often in fragmented pieces of words. T__T Don't get me wrong, I am often patient with this but I just thought that this kind of interaction will consume a lot of time and will possibly (hopefully not) lead into misunderstandings.

I just want to know how you deal with it. :)

Thanks a lot!
