No, it’s to discourage boredom.
It’s fun, but not as much fun as disposing of fluorescent tubes.
I lift every individual egg about an inch out of the carton to make sure it is not stuck or cracked on the bottom.
Since eggs has been asked and answered, I want to mention that this same rule holds true for glassware and crystal.
Years ago, I worked inventory at a high-end department store. Several times, I worked in the crystal, china, silver department. Glasses tend to be sold in sets of four or six. If I came across a set or sets that had a broken member, I was to assemble as many good sets as I could and destroy any broken or incomplete sets. In other words, if the glasses came in a set of four and one was broken, I had to destroy the other three. This was to discourage pilfering by employees.
It was very satisfying to smash expensive glassware in the dumpster.
Same here. And last time I bought eggs at my local Harris Teeter, about a month ago, I could not find a any cartons free from cracks in the size I wanted. So I found a carton with two good eggs and a bunch of bad ones, then switched out the two bad ones from the carton I was holding.
Many moons ago when I was a lad, I worked in a supermarket as a bag/stockboy. When we had cartons of expired eggs we were supposed to destroy the eggs and return the empty cartons for credit.
My boss managed to get a bunch of cartons with no dates on them - don’t know how, but he was shady. He made us put the expired eggs in these cartons and return them to the shelf. He then returned the old cartons for credit. The upside was since the new cartons had no dates, they could stay there forever!
Thankfully that supermarket chain has gone out of business. But I still don’t buy eggs unless they have the date printed on the shell, not the carton. My old boss can’t be the only cheap criminal manager out there.
I open the carton and sort of pinch the pairs of eggs together, thus minimizing the time that I spend checking for cracked and leaking eggs. And I feel no shame in swapping, if the first three or four cartons have undesirable eggs in them.
I have chickens, so I never worry about cracked eggs at the store
