A-San要借手機

A－San想上網，因為佢唔可以去藥店藥房買止肚痛藥。唔過佢有個問題。A－
San而家喺香港一間細細餐廳。，喺嗰度嘅人唔多。佢哋部手機係舊嘅、唔可以上網嘅手機。A－San 點算dim siu［怎么办］啊？ 佢部手機好舊，唔好用。唔可以上網。唔過喺餐廳啲地人部手機都好舊。意大利黑手黨嘅人部手機都唔可以上網。細佬部手機都唔唔好。

A－San雖然好蠢，但係佢都鍾意睇其他人部手機，所以佢知道，餐廳細佬(do you mean Boss 老細 or Brother 細佬?)太太部手機好新，可以上網。唔不過因為太太好鍾意隔離武術館嘅師傅，佢而家唔喺餐廳。 

A－San知道，師傅嘅女朋友喺一間加油站做返工，因為A－San同埋師傅嘅女朋友喺餐廳裡便飲過茶。 佢都知道，嗰個間加油站隔離有間小小嘅藥店藥房。 加油站叫「中國加油站」所以A－San想上網睇一下，有無「中國藥店」。（佢諗 or 估想，「中國加油站」隔離嘅係「中國藥店」。）所以佢要上網睇一睇下。

A－San喺係度睇咁餐廳細佬部手機。老闆用嘅手機係太太嘅，所以老細用嘅係「Kitty貓」嘅手機。A－San知道，「Kitty貓」嘅手機唔可以上網，但係佢都知道，太太而家有啲新嘅手機。A－San上想借餐廳細路太太嘅手機，但係太太唔喺餐廳。佢喺隔籬武術館，同埋師父傾緊偈。
