I had a great manager that did similar things. His education was the navy and he ran a store like a ship, and everyone loved it.
He was a leader not a manager or supervisor, a trait I’ve found common among military people.
He took cleanliness and safety seriously from the navy and applied that to the store, the store staff vacuumed and cleaned the store as it was his and we took pride in it from top to bottom and he lead workplace safety efforts very early on.
He ran the store like a family, and he shined his boots every morning.
