stay on task, you get done in a good amount of time. Get distracted, your day can be 12 hours. The supervisor I have is awesome and works well with your availability. Store employees and managers can be jerks but you dont work for them so, let it roll of your back, do your job, get paid and go home..
Also its better to start your days as early as you can because you work around shoppers and they can make your life difficult.
