Do you have straws? 你有吸管吗？
A decade ago when I first went to dine in McDonald's since coming to America, I was so nervous that I forgot the right word to express what I meant, and thus I made a fool of myself.

That day my friend and I agreed to eat hamburgers. When we, holding our trays, happily sat down, I found there were no straws. I looked around but did not find where the box of straws was. I then got up to make an inquiry.

I lined up again. After I waited for a while, the busy attendant glanced at me. Looking at her two big eyeballs on her shiny black face, suddenly my mind was a blank. I was at a loss for words for quite a while and it was not at all easy for me to say, "Do you have pipes?" She asked loudly with a frown （皱眉）"What?" I was so anxious that I made gestures. My friend saw me, hurriedly came to help me out of the predicament (困境，窘境）and said, "Do you have straws? Aha! It was no wonder that the attendant got puzzled why I asked her for oil pipes.
