Drinking alcohol as soon as you wake up?

So last night I had this guy I’ve been seeing over for some drinks, we finished a whole bottle of whisky and had sex and fell asleep, we still had half filled cups left on my bedside table. We woke up at about 8 am... he straight up just poured my old glass into his and drank the rest of the whisky, I went back to sleep and then I woke up at about 9am and he had gone through half a bottle of wine... wtf? Am I weird for thinking that’s weird? I wanted to say something but didn’t want to hurt his feelings.. really bizarre he acted like there was nothing weird about it.
