I'd like the folks on the other side of the cash register or order book to see me as more than just another account. I just want to be a person. I'd like to leave the transaction feeling like a valued customer who is worth their best behavior. Exhibiting good manners does not make a person appear to be weak or wimpy. Rather, it demonstrates that person's maturity and ability to appropriately respond to business situations.
Bad manners are bad business.
Punctuality is just good manners. This is starting to sound too good to be true. A little consideration goes a long way. And it's really all so basic. I think that if, instead of preaching brotherly love, we preached good manners, we might get a little further.
