I have somehow just got promoted to be a Front-End Supervisor. I started working at Costco about 8 months ago and my only experience is in Majors for 7 months and Membership for 1 month. Does anyone have good tips or some things I should know before starting this position? Also I have not used a front-end cash drawer before, what are some good commands I should know? Anything helps. Thank you
