Doctors charge per 5 mins. But the price is different depending on what they are doing during those 5 mins. There are codes that relate to the price/task. I could be why she was upset, ie, she could have used a cheaper code but didn't.
Anyway, at your leisure, find a new GP. If you are going to a specialist you may ask. Usually if you are referred by another Dr you are more likely to get in.
Which reminds me, we need to find a family GP. I didn't have one and ended up having to to go the "emergency" service because no GPs could take me on short notice. & I desperately need to see an allergist too! Is yours good? Are you getting the tests? Can you PM me your allergists name? (PS, I don't want your GP!!
