As my train was not due to leave for another hour, I had plenty of time to spare. After buying some magazines to read on the journey, I made my way to the luggage office to collect the heavy suitcase I had left there three days before. There were only a few people waiting, and I took out my wallet to find the receipt for my case. The receipt did not seem to be where I had left it. I emptied the contents of the wallet, and the railway tickets, money, scraps of paper, and photographs tumbled out of it; but no matter how hard I searched, the receipt was nowhere to be found.

I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say he had heared this type of story many times and asked me to describe the case. I told him that it was an old, brown looking object no different from the many suitcases I could see on the shelves. The assistant then gave me form and told me to make a list of the contents of the case. If they were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down.

After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment , it occurred to me that if someone had picked the receipt up , he could easily have  claimed the case already , Fortunately this had not happened , for after a time , I found the case lying on its side high up in the corner . After examining the articles inside, the assistant gave me the case . 

I took out my walled to pay him. I pulled out a ten-shilling note and out slipped my “lost” receipt with it! I could not help blushing . The assistant noded his head knowingly, as if to say that he had often seen this happen too!!

The writer found the receipt
