A former 7-Eleven franchise owner from Boston has started a rival convenience store named "6-Twelve" to get back at the company that treated him like a "slave."

Abu Musa—who opened a 7-Eleven franchise in 2005— reportedly got so fed up with the company’s business practices, he decided to open up his own store across the street from his old store location, according to WBZ.

When he first opened, Musa claims his store was doing well but the convenience store owner claims the business went south when he was asked to start carrying food items like pizza and wings. Musa said that he didn’t want to carry hot food at the store because it didn’t sell well and was costing him money.

“[The hot dogs and taquitos would] sit there on the rollers, no one would buy them, and every day I would throw out $200 to $300 worth of food that I had to pay for,” Musa told Boston Globe.

Despite Musa's strong opinion against carrying ready-to-eat food, 7-Eleven told Musa he had to continue carrying the hot food in addition to offering pizza and chicken wings.

Besides the disagreement over what products to carry, Musa says the company began treating him poorly and accusing him of shady business practices.

“7-Eleven didn’t treat me as a partner anymore…they treated me as a slave,” he told Boston Globe.

Musa eventually had his franchise revoked and filed a countersuit against the company, which was settled in court for an undisclosed amount, Boston Globe reports.

Though the suit may be over, Musa's personal battle with the convenience store chain has just started.

Musa decided to seek revenge, opening his very own store across the street from 7-Eleven and naming it 6-Twleve. According to the Globe, many of his old customers followed him across the street and business is growing slowly.

But Musa has lofty goal regarding the fate of his old 7-Eleven.

“My goal is to get them to close,” Musa told The Boston Globe.

Since he knows what 7-Eleven charges for most items, Musa said his strategy is to simply undercut the big guys by selling everything for less at his own shop. Everything except hot food, of course.
