朋友的儿子小冲是做家电维修保养的个体户。一次,他冒着火辣辣的太阳,去开发区内的一家日资企业,为总经理办公室修理空调。日本总经理见他手脚麻利,很快就让一台别人修了几次的空调正常运转了,忍不住夸奖了两句。小冲笑笑,用日语对答。
总经理十分惊讶:这小伙子貌不惊人,却能说一口流利的日语。
“我以前常常读一些翻译过来的小说,可有些不过瘾,就想读日文的杂志和报纸,所以去学了日语。”小冲说,“多学会一种语言,多一种本事,我们在日本企业干活就方便了。”
他们用日语交谈了一会。也许是为了表示对这位小伙子的赞许,总经理破例地让秘书给小冲在公司餐厅安排午饭。
吃完饭,小冲把不锈钢盘子送回餐厅窗口,同时按照午餐的价格,付了五元饭钱。他的帮手有些纳闷,不是总经理请客吗,为什么还要付钱呢 小冲笑道:“他请我们吃饭,是他对我们的尊重。我们付五元饭钱,是我们对自己的尊重……”

A.有些纳闷

B.没送盘子

C.不想付钱
