I really get pissed at poor customer service in a physican medical practice like the following post on Facebook- thank goodness he or she didn't call out the actual practice and doctor name:
Really sucks when you are on time for your dr appointment. You wait 30 minutes before they call you back, then you sit in the room now going on hour waiting for the doctor. Then you have to pay for parking. The longer wait the more I pay to park.
