Dd7 had a check up booked for today at 1.45. We went out this morning and left in plenty of time to get back. Unfortunately there was an accident on our way back and we were held up. DH called the dentist and explained saying we would be slightly late. Got there 4 minutes late and the receptionist spent 4 minutes finding out if we could go up. They said she couldn't be seen as we were late so h got a little stressed and said 'last time we were here we waited three quarters of an hour to be seen!' Dentist wouldn't budge. AIBU to be astounded and appalled??
