I worked in the industry for a few years, and have done a lot of different jobs.
Working with Chef's is very scary...they seem to like perfection, and scream a lot!
I have also worked in Fast Food, and other venues.
When I was still at high school,I had the absolute pleasure to work in a lovely little Chinese family owned restaurant where I learned such a great deal about the preparation and serving of Chinese meals. I also was fortunate enough in my final school year to work in a very good Italian restaurant,where I again learned so much about the industry. I enjoyed both of these jobs immensley.
That's what a waiter/waitress does in a cafe etc.
