Having a loyalty card for a store you shop at regularly can offer great benefits.

This man shares an experience in the supermarket when he encountered a “Karen.”

The entitled woman wanted to use an offer that was only available if you had a loyalty card.

She told another customer she wanted to use his loyalty card, but she probably didn’t understand the consequences.

Use my loyalty card? If you insist

The supermarket I usually go to has a loyalty programme.

It involves a card with a unique code.

This entitles you to extra discounts on some products and sometimes, an offer valid only with such a card.

An entitled customer demanded this man let her use his loyalty card.

So I was shopping, and the Karen behind me apparently had an offer valid only with the loyalty card, so she demanded that I let her scan my card.

I sputter a bit, but she rebutts me with:

“I know how those cards work. Don’t be silly, and let me scan that card.”

He eventually gave in.

I gave in, and let her pay for all her shopping with my loyalty card.

The total was something like 100 euros.

The reason I didn’t want to hand over my card in the first place:

On the loyalty programme, you can activate “automatic savings.”

And now, he acquired a bit of “invisible” savings.

Each transaction is increased by 1%, which goes into a kind of savings account.

If you have saved 65 euros that way, you can have 70 euros paid out which is a nice way to save invisibly.

Thanks for your contribution, Karen!

She should really get her own loyalty card.
