That simple phrase causes me enormous grief. If I could, I would remove it from every product unlucky enough to carry it. My life would become much simpler, and I'd be happier for it.
Unfortunately, removing the best before date would probably piss off customers. Customers love those dates. Changing one digit—increasing the best before date by just a single day—causes customers extreme joy.
Customer: "Excuse me? Do you have any salads with a later due date? If you can find me one, I'll bear your children."
Me: "I have one right here. You don't need to bear my—WHY ARE YOU GETTING NAKED?!?"
Customer: "BE MY BABY DADDY!!"
That's happened to me more times than I care to admit.
You see, customers mistakenly believe that products with a later best before date taste better. When customers buy salads with a nearby date, they break down in tears at the realization that they could have bought a newer, more scrumptious salad. Their tears fall on the crisp leaves of lettuce, leaving a salty taste and forever ruining their salad. And it all could've been avoided by buying a salad with a later date—or so customers think.
But I have a secret: That salad's not so fresh. It's been in the back cooler, out of sight, for a week. Store employees have thrown it around, kicked it, used it to mop up spills, dropped it, and wiped the floor with it. But before we threw it around, the warehouse employees did.
So go ahead, enjoy that salad. I don't mind.
