Interaction with customers and addressing problems.
The training videos and handbook
Hire people who are mature and responsible and care about their appearance.
Treat me as a human being and not a job position. Ii feel like I am being treated unfairly.
Treat employees with seniority with respect and offer them better days off than an employee who hasn't completed probation.
Be responsible, be professional look your best, don't come to work long like you slept in your uniform with hickies all over your neck.
