The shoe repair shop was inspired by John's work in a shop during his time in Michigan shortly after his arrival and Matewan, during which he was able to make $50 a week. After he returned to the town he opened up his own shop, repairing shoes by hand, and eventually picked up a staff of around fifteen repairmen. A few years later, after gaining popularity, the store expanded, with the shoe repair workspace becoming the basement, while the upper floor eventually evolved into a department store that sold a variety of goods. Like the Nenni family, many Italian immigrant families settled in Matewan, and some of these were rumored to have been connected to the mafia. Nel Nenni acknowledged this possibility in an interview with the Matewan Development Center, speculating that Atillio and his father may have used some of the extortion techniques generally associated with the mafia.
The store reached its height during the fifties, a time in which Matewan was referred to as a wide-open town, one with a movie theater, bars, restaurants, and even a hospital. This was not long after Atillio became sick and his son, Eddie Nenni, the man many current Matewan residents associated with the store, was tasked with helping his mom run the business. The business fell into debt but these debts were nearly paid off around the time of the Flood of 1977 which devastated many community businesses. The store reopened after the flood but eventually closed to due to depopulation and the ease of acquiring goods from mail services and chain stores in neighboring communities.
