I've enjoyed the fact I walk in to my appointments now, and they acknowledge my e-check in, tell me to have a seat, and I've been in starting with the nurse within less than 5 minutes, every time. My time wasted sitting at the clinic has been reduced significantly in the last few years... Helps they now enforce a if you are more than 5 minutes late rule, the doctor will decide if they can still see you rule...
Otherwise, I answer the questions so the doc can take care of me. Pretty simple, and I don't see some vast conspiracy out there. Trends can reveal when something has changed that should be looked at...
