With his wife sick in bed, a man did the weekly supermarket shopping

[Bad Karma]

With his wife sick in bed, a man did the weekly supermarket shopping. By the time he reached the checkout, his cart was overflowing. Behind him in the line was a little old lady with just a loaf of bread and some butter.
He turned to her and said: "Is that all you have dear?"
Her face lit up, "Yes, it is."
"Well," he said, "if I were you I'd have a seat because I'm gonna be a while."
