Weird story my exterminator told me

My apartments has an exterminator spray for bugs every few months. He comes by and I try to put my cat away because he's an asshole. The exterminator says "I like them as long as they don't bite because I bite back." I laughed at the joke. Then he tells me about this women's house he was spraying for. He said the women told him not to touch her dogs toy because he will bite. He decided to be like Dennis the menace and take the dogs toy and it bit him so he put the dog in a choke hold and bit the dogs ear and the dog yelped and ran away. The lady asked what he did to his dog and he said he bit the dog and she asked him to leave. He laughed and said "I told her I bite back"

Here's my thing. The lady told him if he touched the dogs toy he would bite. So he did it, that's with intention to provoke the dog right? He's a grown adult and knew not to do that and did it just to piss the dog off and then got bit. Then he bites the dogs ear at this women's house who HE'S working for. Exterminating for HER. I just feel like he had that bite coming, plus that is so unprofessional. Am I wrong?

He also asked was I pregnant or do I like milk and cookies. I'm pregnant, but I found that kind of rude. Anyway just wanted to share that story. Very weird exterminator.
