No, ask at another supermarket first and try it. It's nothing. I don't need you at all.
There are so many supermarkets, of course, you can ask the service desk. Just ask him where the human resources department is. Do it. He asked you to say thank you and it was over. And I don't know what position you are applying for, whether it's a cashier or a tallyman. . Or something,
What you asked is not the main point. What matters is whether you can do it or not, and whether you can stick to it. As long as we can stick to it, everything else is a minor problem. After all, you are going to do things, not to engage in interpersonal relationships. So don't be afraid, as long as you have the ability to stick to it, there is nothing to be afraid of. Even if you say that you are excellent, it's useless if you don't do well. There is still a probation period. When you do well, or can afford it, others will naturally look up to you, no matter what attitude others have. They are not the boss, what's more, you didn't provoke them. They may just be tired from work, so don't worry so much. Just do your job. At first, they may be very uncomfortable. Now it depends on your ability and endurance.
