It was hot yesterday and I was in the supermarket, stocking up on (储备) juice and ice-cream. I don’t like such weather and I was enjoying the fact that it was cooler inside than outside, but the lady behind the checkout (结帐处) was suffering. I asked if she was looking forward to getting out in the sun after her shift (轮班) was finished. She explained that she shouldn’t have been working today, but she had agreed to cover someone else’s shift. Now she wished she hadn’t. She felt like she might die!
I paid for the shopping and headed for the exit. I suddenly remembered something I had wanted to get for Julie, so I went back. There on the shelf was a little hand-held electric fan (电风扇) — batteries included — for only £2.
I firmly (坚定地) believe that good deeds (行为) should be rewarded. The checkout lady was suffering because she had done something for someone. Here I had the chance to make sure she didn’t regret that.
I paid for my last two items at another checkout. As I walked past the lady I had been talking to I could see her puzzled expression. Hadn’t I just left?
“I forgot something,” I explained. And I handed her the fan. I heard her saying, “Awww!” and I did see her smile.
