Office spaces are meant for authorized personnel only.

What would you do if you saw a customer in an employee only area?

This muffler shop owner was shocked to see a customer inside the office area of his shop.

Even worse, the customer was tinkering with the shop’s credit card machine.

What she said left him baffled and frustrated.

Read the full story below to find out all the details.

I’m just helping

As I’ve mentioned a couple other times, I used to own a couple muffler shops.

As with many small businesses, the owner does everything that needs doing, including filling in for the managers when they’re on vacation or it’s their day off.

This man was surprised to see a customer in the office area, using their credit card machine.

Anyhow, I had one lady whose car was in for repair.

And when I came back into the waiting room/office area, I found her punching buttons on our credit card machine.

It was a separate machine from the register.

This was obviously very odd.

The lady said she was helping out by getting a preauthorization.

Customers don’t mess with the credit card machine.

Especially since it’s located 5+ feet behind the counter.

No wall or gate to stop her but what for most was a definite psychological barrier of “public area” v. “employee area.”

“I was helping out by getting the preauth.” Arrrgh!

Some customers are oblivious to boundaries.

Let’s read the responses of other people on Reddit to this story.
