As a provider, there are at times when miscommunication occurs... which is too bad because in this industry it probably means that someone, or both parties are going to be angry, or at least quite upset.
To all CLIENTS: Please understand that we as providers "have heard it all" and most likely we have "been through it all" and so when it comes to details about the appointment, unless you ask about specific details during the phone conversation (either setting of the appointment, or during the confirmation call) we as providers WILL ASSUME YOU HAVE REVIEWED OUR WEB SITES FOR THE MOST UP-TO-DATE INFORMATION. This will save embarrasement and unmet expectations.
And when it comes to "negotiations" with providers... do you  negotiate with your lawyer, dentist, or doctor? When their "prices change", do you say, oh, Dr. Michaels, I am sorry... I thought you were still running your special on proctology exams... do you think I could get the discounted rate on this?
TAKE RESPONSIBILITY FOR YOUR SIDE OF THE AGREEMENT CLIENTS, because we as providers do every single day!
