I recently wrote a post entitled Smugness Equals Entrepreneurial Opportunity that suggested that a business that acts smugly or arrogantly should be sending a welcome message to entrepreneurs to steal their customers from them.
In his blog post, Where do you park?, Seth Godin, discusses a similar issue. He talks of a bank manager who parks in the bank's small parking lot rather than parking down the street so that customers can park closer. While as a customer, this should annoy you, as an entrepreneur, this should excite you. Whenever you see business people behaving badly, jump in there, create something better, and take their customers away from them!
