obviously its a tough situation for you.
I understand it would look better on your college transcript, but
your only 15, so its not like another opportunity wont arise to work somewhere with animals in the next 4 years.
But u also have to realize, a lot goes on behind the scenes. I work at PetCo, and i see some stuff that most people would be appalled by. A lot of times, as long as the customers (zoo go'ers) think the snakes are happy and healthy, then thats all they care about it.
