"There's a bite out of this!"

I have a funny story that happened last night to me. My roommates and I went to Carl's Jr. because Cha (my roomie) said she was in need of greasy food for the evening. We got there and I ordered the 6 dollar guacamole bacon burger (MMMM so GOOD!!!). I get my food and I sit down and take a bite of the burger and got a mouth full of mustard, ketchup and pickles. In my defense, the burgers are pretty big and wrapped in white paper so you can't really see what's inside them unless you unwrap and such, and I didn't I just dug in. So I take the bite and it's obviously not the burger that I ordered. So I went back up the counter and said, "I'm not sure what kind this is, but I ordered the Guacamole Bacon burger and this isn't it." The manager doesn't say anything to me, she just takes my burger and then a couple minutes later she hands me and new one and says, "here you go." A couple minutes later, I'm sitting down at my table and I hear someone at the counter really upset saying, "I've never seen this before! There's a bite out of this burger! This is insane! Yes, there's a bite out of it!" At first I was horrified and felt like dashing out of there before someone came and got me. I knew it was mine. But then I realized, I didn't really have anything to do with it. If someone hands you back a burger, isn't it the manager's responsibility to LOOK at it!?! And especially not give it back out to the public. What if I had laced it with anthrax or something? We all sat in the back kind of snickering at the whole thing and then left. It was pretty funny. Surprisingly enough the woman who got my burger and her husband still stayed. I think if that happened to me, I would boycott the restuarant.
