I had an experience like that, but not as bad as yours. I had a veiled chameleon that I was treating with antibiotic shots, but the poor guy was getting worse. Instead of letting him starve I decided to take him to the vet (not the exotic vet I take my birds to) to be put down. Anyway, the doctor was writing down all my info and I had Frank (the chameleon) in a towel on the examining table. She flipped her hand and the towel went flying across the table. I was super mad and just remembering it I'm still mad! I jumped up off my chair and grabbed him and started petting him and seeing if he was ok. I hope that witch got the message!

Anyway, I would go to the other vet if I was you. You don't need to be dealing with a vet that treats their career like a job. Come on, she's not washing cars, she's taking car of living things and she should be more compassionate. (I'm not saying there is anything bad about having a job where you wash cars. Just that living things need more compassion than cars/objects). When I have a bad day maybe a few invoices have errors or something like that, but if I was a vet I would treat every patient like gold! I’m sorry for being so mad, but that is ridiculous. Plus, who cares that the dog was returned so many times! Would that vet rather have the dog put down!?!
