I am a cashier, so I don't need to update my skills since the duty will always be the same.

Keep yourself updated and watch some videos about how to deal with each situation. It is essential to keep practicing since the work of a cashier can be difficult. You should execute the duties very carefully as you contribute directly to the profits of the establishment. Always look for developing your skills.
