Make sure your employer has a time clock or at least a sign-in and sign-out sheet. There are some employers in town who only pay you for the time they have written on the schedule instead of actual hours worked. Arriving 15 minutes early and leaving 10 or 15 minutes after closing and not getting paid for it adds up to a lot of savings for the employer throughout the season. Especially when there are multiple employees who are being taken advantage of.
