People left at Niagara on the Lake because there was an incompete Store Manager who would rather party than help her team out and flirted with the guys and was intimidated by the girls. That is what I would suggest you not do when you are a Store Manager.
Talk to your employees, get an understanding on how you as a Manager affects everyone and not ride the high horse and be clique with your friends who you just want to party with.
Good communication, team work...
Listen to worker feedback
