Probably nothing. Some people, usually women, use the term Dear with anybody. I've had waitresses and store clerks use it. It is just the way they were raised. Southern United States it is very common. That and Honey. I think both are a little personal, but it's no big deal. It is just them being friendly instead of using Sir, Ma'am, or Miss. Also, they may have forgot your name and that covers them.
The British tend to use 'pet' in much the same way as we would use 'honey' or 'dear.' It can be condescending, or it could be just a quick way to refer to someone.
