There’s good business. And then there’s bad business, the kind of business practices that will lose you customers and win you nothing but complaints and badmouthing.
If you want to grow your small business or even keep the clients and/or customers you have now, you never want to:
1) Be personally offensive.
It’s not just about image; it’s about behavior. You can be perfectly dressed for the job at hand but if you have a sewer mouth, make racist or sexist remarks, or stink like a goat, you’re going to lose a lot of business.
And if you actually urinate in a bucket in a customer’s garage, as one garage door installer did in a televised episode of Marketplace, you might as well leave town.
