It is sad, because it all links back to money. The more customers they can fit in the more money they make. It is terrible.
I live in Australia where there is bulk billing and this is the standard procedure, cram in as many people as possible in the day, and get each appointment done in preferably 5-10mins. Unless you go to a clinic owned by an individual doctor, you are pretty much guaranteed an extra 15mins, and most of the time 30-60mins.
It's disappointing but I can't complain considering it is free for us through Medicare.
