Here's the part of my job that I'm starting to hate: CUSTOMERS.
I got the sh*t kicked out of me by an Argentine Tegu yesterday because the customer spooked it. You should have seen the amount of blood this thing got outta me, and the scars I have on my hands & wrists now. All because the customer decided to try and pet the tegu's HEAD after I just got it calm.
Not to mention the number of customers I've had to say "No, you should not feed your boa a live rabbit!" or "No, you should NOT house your BP with your corn snake!". I kid you not - I just had to tell someone that yesterday.
I still love the rest of my job though.
