Sometimes the smallest moment at work turns out to be the most meaningful thing you ever did.

When a convenience store worker instinctively grabbed a regular customer’s usual pack of cigarettes before she even asked, the interaction that followed was so unexpectedly honest that she never came back to buy them again.

Two years later she walked back through the door — not for cigarettes, but to tell him she had quit the night they spoke.

You’ll want to keep reading for this incredible story.

According to my best friend, I may have saved a life.

About two years ago, I had a regular customer. She’d come in every single night and buy a pack of cigarettes — sometimes two.

One day, she came in and I instinctively grabbed her cigarettes before she asked for them.

The most dedicated customers appreciated this efficiency.

Believe it or not, my regular smokers actually like this.

It makes the transaction quicker. They come in, I grab their Marlboro Lights, they buy them and leave.

Simple.

But then one shift, everything changed for one customer.

Not this customer. Not tonight.

When I grabbed her usual cigarettes, she looked startled, and for some reason I said “Oh, wait. Do you want two?” and she looked at me, then the cigarettes, frowned and said “Oh my God. I’ve gotten to a point where I buy cigarettes so much you recognize my face and know my pack. I think I won’t be buying any tonight.”

And I never saw her again.

This cashier didn’t recognize the significance of this at first.

I didn’t even think about it, really. I don’t know why I never noticed the connection between her not buying cigarettes and her never coming into my store after the fact.

I suppose it was because I’m always busy and I have 50 other regulars, so it never crossed my mind more than “Whatever happened to Virginia Slim Blues?” every now and then.

Today, she came back, but it had been so long I forgot her face.

But the customer had remembered his.

We had a bit of small talk and she said “I didn’t recognize you without your ponytail.”

I stroked my now short hair and said “Whoa, I cut that off something like two years ago, dude. Did you stop coming here or something?”

She said “Yeah, I quit smoking,” and it all came back to me.

Apparently, their past interaction made a huge impact in her life.

I asked her if it was from that night so long ago and she nodded her head and said she quit the moment that interaction happened.

When talking to my best friend about it today, she said I very well could have saved her life — or at least helped her live a few years longer.

This was all really nice to experience today.

He finds himself at a crossroads in his career, and he thinks there may be better things ahead for him too.

I’ve been really shaky with my feelings on the company I work with, and I’ve been job searching for a few days now. I’ve been feeling like I’ve accomplished very little in the four years I have been with the company.

About an hour after this whole experience with the regular customer, I got a phone call from a company I applied to, and they informed me they liked my resume and wanted to see me for an interview.

I’d say today brought me both closure and a sign.

Seems like everything worked out the way it was supposed to.
