So, after landing my new job as a Walmart greeter—a good find for many retirees—I lasted less than a day. 

About two hours into my first shift, a very loud, mean-acting woman walked into the store with her two kids, yelling obscenities at them all the way through the entrance. 

As I had been instructed, I said pleasantly, “Good morning and welcome to Walmart. Nice children you have there. Are they twins?” 

Of course, her children were at least two years apart, and while they shared some similar features, they certainly didn’t look alike. 

The woman stopped yelling long enough to snap, “Hell no, they ain’t twins. The oldest one’s 9, and the other one’s 7. Why the hell would you think they’re twins? Are you blind or just stupid?” 

So I replied, “I’m neither blind nor stupid, ma’am… I just couldn’t believe someone slept with you twice. Have a good day, and thank you for shopping at Walmart.” 

My supervisor later said I probably wasn’t cut out for this line of work.
