A 'Very Nice' Customer

I had a little shop, with one assistant. She was a cute small girl. Some men came and asked for some products i didn't sell. Furthermore, we had 'very nice' talks. But one minute they've gone, my assistant blamed me for what happened and try to catch them back. When i headed back of my shop, i saw so many dirty dishes then i cleaned them, with a very sorrowful feeling, of course.
