My sister once worked as a cashier from a department store here in our city. She worked for three months. While she was working, they used old cash registering machines. She was not able to use a symbol barcode scanner like the cashiers uses as of this time. She said worked was more tedious because you have to punch the price manually. If you wrongly priced an item, you get a memo from the supervisor and will be asked to pay for the shortages.
Anyway, the only thing a cashier can be of fault nowadays is from cash shortages. Because of barcode scanners, they will never have a problem on prices! Life is simple!
