A story happened on me.... (This is not a story about something happening to you! This is a story about you something you did, so therefore, the title should be "my excursion to the supermarket")

Excusion means: a short trip for a special purpose with the intention of a quick return

One day, I paid a visit to the supermarket near my home to do some shopping. Filling my basket in a hurry, I suddenly had an uneasy felling that I didn't have enough money to pay for all the goods. I  was so anxious that I emptied all the items on to the floor. I fell to my knees and began to [add up] (calculate) the prices.  

Just then a young salesgirl came over approached me. She seemed puzzled about what I was doing... She stared at me for a while. Then she bent down and said "No matter how hard you pray, Sister, we're not reducing the prices. Don't waste your time any longer......"

You write like a person who grew up speaking English. You have a strong sense of comic timing. You tell the story in the correct order so that the reader wants to know what happens next. Are you secretly a writer, visiting this site for research?
