A tacky, rude, selfish customer is observed by a group of musical commentators.
One day a traditional song, that I'd learned as a child, popped into my head and wouldn't leave. I started thinking up new lyrics for it based on a silly situation. And after years of different retail jobs I've seen customers like this; rude, pushy, greedy and talking loudly on their cell phone. Most of the updated lyrics to "When Johnny Comes Marching Home", are sung in a "round" by 3 observing shoppers that act as a Greek Chorus, commenting on a woman behaving badly.
I hope it makes you smile and gives you a giggle or two:-)
