Mcdonalds Employees Please Help? :)?

On my first day I worked on a till with one of the managers. She took some orders and I watched and then followed her around to find out where everything is and how it works. After about 15mins I was taking orders and then the next day I took orders but had an another worker get the food for me. On my third day I was on my own but there is always a manager or two around to grab when your confused and swipe the till when you get an order wrong
