Try being a butcher...
“I just asked a customer to leave and she was not too pleased about it. She had shopped here earlier and bought a chicken from the meat department, where she was assured that all our chickens are hens, not roosters. She came back around 9 pm because she was certain she had been sold a rooster. She was arguing with the meat managers and generally pitching a fit to the extent that they called me in.
She said she could tell it was a rooster by putting her hand inside the chicken’s cavity and was convinced that she had felt (in a hushed tone) testicles. Now, I do not know how to sex a chicken, but I have been told by our team members that we only carry hens. I offered her a refund, but she did not want this.
Instead, she wanted to stick her hand in all of our chickens to feel if they were hens or roosters. I told her I couldn't let her do that.
She called her daughter who pretty much repeated exactly what she had already said. This whole thing went on for about 5 minutes going round and round. I told her that she was going to have to take a refund or leave. As she continued to argue with me I walked her up to the customer service booth. As we gave her a refund she kept at me. I told her that she could go buy another chicken and leave, but she kept arguing with me. So then I told her she had to leave. She yelled and screamed as we slowly ushered her out the door. She continued to argue with James until I asked him to please walk away from her so she would stop yelling.”
By the way, the Internet (are we still capitalizing that?) Anyway, it's not helpful if you want to learn "how to sex" a chicken...just how to have sex with a chicken, which is foul. (I was sooo tempted to put "fowl")
