As the scene began, the pregnant woman walked toward a man in a bright blue T- shirt and asked whether she could step ahead of him in line. Taking one look at her, he said yes.
Then, the woman's husband -- played by our burly male actor with the shaved head -- joined her in line, pushing another overstuffed shopping cart. When the man finally realized what had happened, all he could do was laugh.
"I like to be courteous to people," Jesus Berrios told us later. "I saw the young lady was pregnant so I just moved to another register."
The pregnant woman was an actress working for us. And she's not really pregnant. She was wearing a prosthetic belly.
But would everyone be as sympathetic to our pregnant woman?
When she asked one older man whether she could cut in front of him, he responded: "Why?" When she responded, "I don't feel good," the man just stood there, stone faced.
"I understand she's pregnant," said Lawrence Rosso. But that wasn't a good enough reason "because I felt she was just trying to crash the line."
A woman in short red hair and black-rimmed glasses seemed only too happy to let the pregnant woman -- with her two items -- cut in front of her. But after stepping away for a few seconds, she returned only to find the pregnant woman's husband and their overloaded shopping cart parked in front of hers.
"Oh, with all this? No! I thought you only had two things."
Then the husband got into the act, suggesting that the other customers in line might also have more than 10 items. When he began to count the number of bottles in a shopper's case of soft drinks, the crowd erupted.
"You want to count the pretzels?" asked the man with the soda in his cart.
"You can't be real," said shopper Kathleen Fleming. "I can't believe you're still here. Are you insane?"
It seemed Fleming has very strong views about fairness and supermarket etiquette.
"Once you take a rule that you follow to be polite and courteous and you get rid of it that one time," said Fleming. "The next time it becomes easier. And before you know it, people are doing things that are seriously wrong. You have to respect those around you or everything just crumbles."
As another fellow shopper reacted angrily to our pregnant woman, shopper Kathy DePippo was taken aback. She said, whether on the express checkout line or anywhere else, people need to slow down, take a breath and try a little kindness.
"People have reasons to ask for a favor," DePippo said. "I don't know many things you can't wait another 10 minutes for."
