Waiters mainly train service flow (the whole process of catering service) and hotel etiquette (standing posture, sitting posture, walking posture, smiling greetings, etc. ), and military training is necessary. While exercising their etiquette, strengthen their sense of obedience and lay the foundation for later training.
Don't be afraid, that's what it is. It's good for you to stick to it.
I have been a star hotel manager for 2 years. If you don't know, you can always ask me.
