-Can I return this phone if I don't like it or if it doesn't work well?
-Yes, you can but... why wouldn't it work well?
-Well, I bought a cell phone in the past and it didn't work well. I couldn't hear people well and people couldn't hear me. I tried to return it to the guy who sold it to me but he didn't want to give my money back. From that day on, I always check my_rights/the_rights_I_have before buying anything.
Please, is this dialog fine?
That's very good.
