“Every Trade Has Its Master” 「三百六十行 行行出狀元」

I am still wondering as to how that young man had managed to remember which car was whose; which key belonged to which car, which car was parked where, and who was going to leave when...我到現在還在納悶:車場裏有那麼多車,幾百部是有了,他怎麼記得哪部車是誰的、哪串鈅匙是哪部車的、哪輛車又停在哪裏的、哪個人又將何時離開???
