He added a camera angle to the commercial pump.
Two weeks later, he reviewed footage.
The HOA president arrived at 5:40 a.m.
Not in the luxury SUV.
In a borrowed landscaping pickup carrying a rectangular transfer tank in the bed.
She swiped the association card.
Pumped ninety-seven gallons.
Left.
Three days later, same truck.
Different driver.
One hundred eighteen gallons.
The owner traced the truck.
It belonged to the association’s snow contractor.
That could be legitimate.
So he called.
“Are you fueling HOA equipment?”
The contractor manager said:
“No.”
The owner looked at the transaction record.
“What about the transfer tank?”
“What transfer tank?”
The owner’s concern deepened.
He requested written authorization from the HOA.
The president sent a short response.
Community emergency storage. Existing board authorization. Continue normal billing.
The owner asked for the storage-tank registration.
No response.
He asked again.
Nothing.
Then something strange happened.
The HOA stopped buying fuel during business hours.
Transactions shifted almost entirely to early morning and late evening.
He changed the commercial pump settings.
After-hours fuel purchases above fifty gallons now required secondary authorization.
The very next morning, the HOA president called him personally.
“Why is our card declining?”
“New control.”
“You don’t apply that to other accounts.”
“I apply it to any account with unexplained bulk transfers.”
“You have no right.”
“I sell the fuel.”
She threatened to move the association business elsewhere.
He said that was fine.
She did not.
There were other stations.
But none nearby offered the same credit terms.
The family station gave the HOA thirty days.
No annual membership fee.
Emergency storm access.
And wholesale pricing once volume exceeded a threshold.
The president wanted the arrangement.
She just did not want questions.
Then came the first clue about the underground tank.
A maintenance worker stopped at the station for coffee.
Older man.
Association employee for fourteen years.
He recognized the owner.
“Your guys still servicing storage tanks?”
The owner looked up.
“Depends.”
“Association’s reserve pump is acting weird.”
The owner’s expression changed.
“What reserve pump?”
The worker pointed vaguely east.
“Behind the clubhouse.”
“Above-ground?”
The worker frowned.
“No.”
“Buried.”
The owner felt cold.
“How big?”
“Don’t know.”
“Old tank.”
“How old?”
“Before my time.”
That made no sense.
The subdivision itself was only twenty-five years old.
