對住西人真係好煩! 我話 Thank You ! 佢就話 You are welcome ! 咁.我..

I am a native English speaker, maybe I can help. On this situation, you don't have to say anything, because he/she provide services to you, and if you don't need he/she any other services, then say nothing.

Actually, you can say goodbye to him because the conservation is finished. But you can say: You are welcome, also!

其实和我们用广东话一样,我说多谢您,然后您说不用那样和我客气嘛.通常我就不用再讲什么了.西人和唐人一样的.

You are welcome 姐係5洗客氣
