This is equivalent to changing careers! However, the cashier really can't live a wonderful life! It takes experience to find a job now. Many people see, ah, what they want for more than 3 years, even 5 or 6 years, have just worked or haven't done it before, and they don't have the courage to apply! This is actually a very wrong idea. You should apply, mainly because you are sincere enough to show the spirit of positive efforts. People will definitely want you! After all, you don't need professional knowledge to do sales!
