A few weeks ago, Jeremy Bradley talked about customer service nightmares. (It's almost become a yearly tradition on this show.) But, in his latest rant, he spoke from the perspective of a business owner and what bad customers can do to a company.

He says being way too serious and too corporate is bad for your brand.
