To begin:
Honesty prevailing, you generally can’t get into this level of work without at least 1 year of customer service experience and some relevant experience managing people and money. These experiences don’t necessarily have to come from the food service industry. They can come from a wide variety of fields. If you really want to go straight into management, see if the local sit down chain restaurant has a “manager in training” program of some variety. Be aware that you may start at a lower pay rate thru this program.
Before entering management, make sure you bone up on your intrapersonal skills and basic math. Both of these are essential for managing people and costs.
