英语翻译
Allow me to fetch you a chair.
—Thank you,but I've just asked the waiter to get me one.
—Let me get you a drink,then.
—Thank you again,but look,John's bringing me one now.
—I don't seem to be very useful,do
—Don't say that.There's always another time,you know.
最后这两行怎翻译呢

—I don't seem to be very useful,do
看来好像用不到我是吗?
—Don't say that.There's always another time,you know.
不要这样说,你知道总会有用的到你的时候.
