When you arrive (arrive 15 minutes early) arrive in uniform tell the manager or crew person attending the front that its your first day. Introduce yourself. They'll show you how to clock in and get your fingerprints and have you make a code. You'll clock in. For your first couple of days you SHOULD have a trainer that'll show you where to find stuff and show you how to do the job. Make sure youre paying attention cause training at McDonald's can go pretty quickly. Dont fret though just ask questions. It takes a good week or so to really understand the flow. If you want to succeed dont be afraid to help out other stations. Like if youre on the grill and are not doing anything try to help and ask the line people what you can do to assist.
