A group of Nuns opened a Flower Shop.
The Nuns started selling small bouquets, and after some success moved on to larger arrangements.
Their business grew enough that they were eventually the only place in a ten kilometre radius to sell flowers; and gathered a monopoly on the market.
One day, a couple of Friars opened another greenhouse and flower shop right across the street!
Their products took time to be recognised by the local market, as the Nuns had a tight grip; but gradually the Friars started taking business.
Seeing that they were not going to have a successful business soon, the Nuns decided to push the Friars out of the community.
First they snuck into their shop one night and started a fire. The community volunteer firefighters were able to extinguish it quickly, with little damages.
Then the Nuns tried to tarnish the Friars reputation by spreading rumours about their Flowers supposedly being GMO abominations.
Customers saw through this, and the rumours dissipated quickly.
Finally, the Nuns hired a local thug named Hugh, who had a panache for destruction.
He took a weed-whacker to the Friars shop, then drove his truck through the front door, spraying herbicide over everything.
The Friars, of course, had no option but to pack up and leave town; leaving the Nuns to their flower monopoly.
... Leaving us to realise that Hugh, and ONLY Hugh, can prevent Florist Friars.
