I went to dentist for my tooth ache with my daughter.
But I waited for an hour at meeting room of dentist. And I was let into a treatment room. I took x-ray and I was waited for 20-minute again. While I wait, they who came after me, took treatment, went out the room. Why???? Finally, I decided to go home without treatment. Yes, I was angry about that.
I never go to that dentist. But if they say sorry what you have been waiting such a long time, I never got angry.
