People forget all too easily how important “word of mouth” is in maintaining a business. It is more important than any type of advertisement they might put money out for. One bad reference to a business can cost them 10 customers. Boom just like that.
If you own any business and you what a good customer base, then provide excellent service that people want to talk about. You’ll save lots on advertisements that can’t do anywhere near that much good. Don’t give your customers a reason to complain.
And on the customer side, if you are rude, dishonest, overly picky and just plain crabby stay home. That is where you belong. And folks, believe me I have served people in the banking as well as the food industry. There are some people that think the world owes them an apology because they exist. It owes them nothing.
