Incremental Chain Reaction: The Forgotten Supplier

Jim liked the feeling of a fresh start.

Three weeks earlier, he’d switched his supplier for paper bags. The old company had become slow, unresponsive, and a little too familiar. The new supplier was everything the old one wasn’t. better value, friendlier on the phone, and always happy to help. Every Thursday, without fail, a new stack of bags arrived at the shop.

It didn’t take long for the new routine to settle in.
The deliveries were reliable.
The service was warm.
The bags were better quality.

It felt like a good decision.

Months passed, and the new supplier became part of the rhythm of the shop. Jim trusted them enough to share the same access code he’d once given the old supplier. the one that let them drop bags inside the store before opening. It saved him time, and it had always worked smoothly.

Until the morning it didn’t.

Jim unlocked the door one Tuesday and felt the wrongness immediately.
The till was open.
Coins scattered.
Shelves disturbed.
Products hanging at odd angles, as if someone had moved through the shop without care or familiarity.

But on the counter, neatly stacked, were the paper bags.
Just like every week.

Jim’s stomach tightened.

He walked straight to the back office and pulled up the CCTV.
The footage told the story quickly.

A figure entered the shop in the early hours.
Not by force.
Not by breaking anything.
They simply keyed in the code and walked through the door.

The person wore a cap pulled low, as if trying to hide their face.
But the disguise wasn’t good.
Jim recognised the shape of the coat, the way the shoulders hunched, the familiar shuffle of the walk.

Bob.
From the old supplier.

Someone who used to have legitimate access.
Someone Jim had trusted.
Someone he’d forgotten to remove from the chain.

The realisation landed quietly, without drama.
A small oversight.
A forgotten detail.
A link in the chain he hadn’t checked because everything else felt settled.

Jim changed the code that morning.
He updated his notes.
He added a new line to his mental checklist:

“When something changes, check what hasn’t.”

Because trust isn’t just about who you let in.
It’s about remembering who used to have the key.

Small routines protect the shop.
Small oversights expose it.
And the chain reaction works both ways.
