I went on a service call tonight. Right out of the gate I could tell the dude was pretty sketchy but he was very friendly. No front teeth so he's probably a meth addict. As I'm finishing up my work, his 2 daughters (probably 13-17 years old) came in and asked the guy to take them to get Halloween stuff. I could tell he wasn't saying it out of anger or malice, but he called them a couple of bitches, said one of them was a fvcking whore just like her mom, said "you just want to go get laid" to one of them, among other things. His girlfriend, who owns the house and seems pretty reasonable was standing there while this is going on and I kind of gave her a look to let her know that I didn't think this was OK, and she gave me a look that was kind of like "I don't know what to do". I ended up saying, "dude, don't talk to your daughters that way". Not in a threatening way, but he knew I was serious. He laughed and started to go on about how his ex wife had the one daughter when she was 15 and she's a whore but he had a kid when he was 14 so "i can't talk", then proceeded to kiss my ass for coming over on a Friday night to fix the problem and I have a repeat customer, blah blah blah. I have to go back tomorrow and he's not going to be there but the girlfriend is. Do I ask her if things are OK around there or just mind my own business?
