I was at Evil Big Box Store #1812(tm) this evening talking to a customer service manager, whom I worked with when I was employed there part time from 1996-1998. She was telling me that they don't hire people to work the hours I worked at that time.
She also told me that they don't want people making announcements on the public address the way I used to. Funny how businesses are all getting away from the personal touch. It seems the cashiers are getting away from the "thank you for shopping at..." more and more. Perhaps some of these businesses would quit losing customers to the internet if they would try personalized service a bit more often.
I also saw recently a situation which could have been avoided when I was cashiering. At another department store this man paid for about 4 dollars worth of merchandise with a fifty. The cashier handed him his change and the man claimed she shorted him 20 dollars. I suspect this was a scam by the customer. This could have been avoided if the cashier would have counted the change back to the man. But I was told later that company policy forbade that practice. So this store loses some money and the cashier gets written up.
Proper customer service, common courtesy, and some genuine appreciation goes a long way.
