It is best to have friends who are also in the catering industry. Ask them if there are any waiters willing to work for you. Then the waiters can introduce each other. I believe that there will be some soon, because employees are generally introduced by friends who work together, so there are more and more people like this. You can rest assured to hire employees in this way, and you will not be fired at any time. If you hire people from this city, unless you can retain them with salary, they will change jobs at a speed that you cannot imagine.
