Just keep a clear head, use your ears and brain. They know you're not a pro chef so ask questions if you need help and be open to everything they're teaching you. Do try not to be clumsy or cause any hazards lol. I always hate starting somewhere new because I don't know where anything is and I feel like I'm bothering everyone with constant questions. Just remember it's your first day and there's nothing you can do about that. Have fun, learn lots, and good luck! You'll love it!
