I arrived early for my 9:00 am appointment; I am puzzled that no one came out to get me until 9:08 am. I make my appointments early because I want to avoid delays; I keep a very tight schedule for each day in order to maximize my time. It would have been courteous for someone to come out and advise me that there was going to be a delay; that would demonstrate that my own time was considered valuable.
The rest of the appointment was fine; I chose to minimize the "chit chat" of the dental hygienist because I not only wanted to get out of there after the delay, but I didn't want following patients to also have to be delayed because of my own circumstances. I was not trying to be abrupt or rude; I was trying to respect the time of the people who followed me...that's all.
