I've lived for so long, and I'm not as good at chopping vegetables in restaurants as a security guard. It's really irritating. If you cut vegetables in a restaurant, it is not as high as the security guard. Don't get angry, because people have different jobs and different salaries. This is a matter of course. Don't think that a security guard should have a low salary, because although he is a security guard, he has great responsibilities, and he is responsible for the personal safety of the workplace, so he looks inconspicuous.
