The Smile That Cost a Fruit Seller His Best Customer

What 18 months of buying fruit taught me about the psychology of influence

It was mid-2020, the peak of the first Covid wave. Most of us barely understood the disease, but one rule was non-negotiable: keep your distance. Social distancing was the new normal, and like millions of others, I was confined to home, working remotely, staying indoors, avoiding crowds.

One new task landed on my plate: I became the designated "outside person" for the household, responsible for fruits and vegetables.

I'd always bought fruit from the supermarket, but that meant enclosed spaces and more people, a risk I wasn't willing to take. So, I switched to a street vendor near my house, a small stall run by two brothers. I became a regular. Consistent, loyal, uncomplaining. I never compared prices elsewhere, never questioned the quality against other sellers. This continued for over a year and a half.

And yet, more than once during that period, I had a nagging feeling: I'm being overcharged.

The switch that shouldn't have happened

One day, without much premeditation, I bought fruit from a different, considerably smaller vendor instead.

That small decision stuck with me, because it seemed to contradict everything I knew about human behavior. One of Dr. Robert Cialdini's seven Principles of Influence is Consistency. We build routines, and we stay loyal to them almost subconsciously. Switching should have felt uncomfortable. So why didn't it?

I started digging into my own "why." The new seller was smaller, had less variety, and didn't stock imported items like blueberries, grape fruit or dragon fruit. On paper, I had traded up in convenience for less.

The answer, once I looked honestly, was simple: I had been tolerating disrespect. The two brothers at my original stall had grown a loyal client base,  many of us pushed there by Covid necessity, not choice and somewhere along the way, comfort had curdled into complacency. They grew casual, even a little dismissive. And that was enough to push me out of my own routine.

A masterclass in Liking

I still buy from that second stall today. It's run by two brothers as well,  Dileep, the younger, and Vijay, the elder. No matter how many customers are crowding their till, they greet me the same way, every time: warmly, personally, like I matter.

That warmth doesn't switch off when business gets busy. It's consistent, and it's genuine. It's a masterclass in Cialdini's principle of Liking and it echoes something Dr. Gregory Neidert has emphasized in his own work on influence: relationship-building is the first step in any human interaction. Before logic, before price, before convenience, people respond to people who make them feel valued.

But the brothers don't stop at Liking.

Authority, quietly earned

If I pick up fruit that isn't quite ripe or ready, one of them will gently step in and choose for me. I've never once regretted letting them. They know fruit, genuinely, deeply and that expertise builds something Cialdini calls Authority. When someone demonstrates real competence in their domain, we don't just listen to their advice we hand over the decision entirely, and trust it.

Everyone else is buying here too

Over time, I noticed the stall getting busier with more "people like me" choosing it. That's Social Proof at work, and it deepened my own loyalty. When we see several others and similar others making a choice, it quietly validates our own.

And then there's Scarcity. Dileep will sometimes mention, almost in passing, that a seasonal fruit is nearly finished for the year. That single piece of information, “ this won't be available much longer”  has worked on me every time. I've paid well above the regular price simply because I didn't want to miss out.

Two stalls, two different stories

Today, Dileep and Vijay's business has grown. A bigger stall, a steadier stream of loyal customers, real success built quietly through trust. The first stall I used to visit tells a different story. Fewer buyers. A quieter till.

I walked past it recently, and one of the original brothers caught my eye and gave me a warm, genuine smile.

I couldn't help thinking: if he'd smiled like that when I was still his customer, I'd probably still be one today.

Loyalty isn't just about consistency — it's about what a relationship gives back. Dr. Cialdini and Dr. Neidert's principles aren't just for marketers and salespeople. They play out in a two-minute transaction at a fruit stall, every single day.
