should have handed him a broom and dust pan from the cleaning aisle

Cleanup on Aisle 3, Cherry Pits on Floor. I see the 'someone else will clean it up' mentality a lot in TV, unfortunately. That's what they do in their own homes, Perhaps?

And you didn’t say anything? I would. Have called him on it.

I think the same happens with memory loss…

I always think twice before approaching someone acting like this.
He might have two buddy's standing by, Smith and Wesson.

True. I'd be VERY careful. But there is a possibility that he "paid" nevertheless.

My wife always washes fresh produce as soon as we get it home, before storing it. a fifteen-minute soak in water w/baking soda followed by another soak (depending on how dirty the water was the first time), then rinse and spin-dry in a salad-spinner thing she has. You might think this is the definition of anal but I was amazed at the murky-grey color the water gets. This clown was A) eating cherries he hadn't paid for, B) or washed, C) at WAL-MART, where just the looks of some of the people pawing over the produce would give one pause.

I wonder how he felt the next morning.

And a possible shoplifter.

The "Dirty Dozen" top 12 fruits and vegetables with the most pesticides:
Strawberries
Spinach
Kale, collard & mustard greens
Peaches
Pears
Nectarines
Apples
Grapes
Bell & hot peppers
Cherries
Blueberries
Green beans
More than 90 percent of samples of strawberries, apples, cherries, spinach, nectarines and grapes tested positive for residues of two or more pesticides...Eating without washing and he ingested?????

They’re known as Wal-martians. There are web sites devoted to Walmart customers!

Why am I thinking....Dr. Seuss...

Interesting to find blueberries on that list. They are perhaps the closest to wild of the fruits and vegetables we eat. They did far better up north. Here it is too hot and difficult to make and keep the soil acidic enough. Northern birds used to wait for the fruit to ripen here the birds eat them green.
Spray? I never needed to spray.

I do was all fruit. Including melons before cutting into them. Does it wash off all pesticides-probably not. People who pick the fruit. We do not want to know.

Lipstick on a pig. Wonder if he was reducing the weight of the bag before purchase

No. Probably I would point him out to a senior employee (maybe, just maybe, you might find an employee nowadays that would give a damn).
