I was at the dentist today. Second time they made me wait more than 30 minutes. Aside from that they asked for a much higher payment than I agreed to just one week earlier.

I got up and told them I'm leaving and they can keep the money. The apologized profusely and convinced me to stay. They did get me in and out very quickly after that.

I doubt I will go back for the second half of the work.

Also happened when I took my 5 year old son to the dentist. The doctor's policy was that no parents are allowed on the treatment room. I told my son to get out of the chair and left. Turned out that dentist was trying to put fillings in teeth that would fall out before fillings were even needed.
