Chinese people love to joke. If a Chinese is joking with a foreigner, how can he translate it so that the foreigner knows he is joking?

The beer is not gonna the same price next time if you don't do what so ever.

Or,

Yo man, you know. You 've got this beer. You are gonna do something. The above what so ever can also be replaced by itself, similarly

But then again, it’s not necessary. Foreigners are very straightforward. Just say could you please help me with blablabla. That should be fine. Play tricks with foreigners T.T Either you are being played, or they don’t understand what you are talking about
