When you say "her", I assume that you are speaking about Rosanne Herpen. If so, I really can't believe that she was rude to you. This is my second year applying, and for two years she has been extremely tolerant of my constant pestering of the adcom. The other members of the committee have also been very generous with their time. Although I was told in the beginning of my trials that my application was deficient in several sections, I was given a clear and polite explanation of what I would need to do in order to improve my chance of admission.
If your GPA is low, just take classes. If you like penn and there is no way for you to be accepted as an OOS applicant, you have the option of moving to PA. I wish you the best of luck in becoming a vet, but please don't bash my future school. I love UPenn. Penn Vet is inarguably one of the best veterinary schools and research centers in the world.
Most importantly, the students that I've met at interviews and online have been friendly and unpretentious, especially for such an elite school.
I bet that if you were to put the work in and get accepted in the future, your attitude would change dramatically.
