What should I say to apply for this job? Look at the recruitment of optical shops. Want to go in and ask.

Dress generously on the day of application, don't dress too fancy and fashionable, keep it simple and don't wear heavy makeup. Relax and don't be nervous, because sales should give people a comfortable feeling. Remember to keep smiling at all times. Bosses generally like festive people and bring wealth. All you have to do is speak out. It can be said that I have done sales before, and I want to have a try here.
