Помогите составить диалог на тему «покупатель покупает подарок…

тут я думаю легче импровизировать… к примеру: — Excuse me- Hello, may i help you- Yes. Can you show me this present in green box? — Sure. Here is it.- How much does it cost- This present cost 50dollars- 50 dollars? that is too mach- Mmm. how about this? it cost 35dollars- I don't like that one- A don't know what you want… — that is nice. How mach is it? — 30 dollars- That'll be fine! — It is all? — Do you can pack it in good gift box? — Yes. Have a good Christmas- Thank you- Thank you too Писал что пришло в голову, возможно есть пару граматических ошибок, дерзай)
