For the record, I’ve never worked anywhere that this was the case. I mean, yes, if you get hammered and act stupid, that’s obviously going to impact your job (probably, unless you work in the kind of place where your boss is right there with you), but pretty much everywhere I’ve ever worked, people came if they felt like it, had a drink or two and some snacks, and not one person ever gave it another thought.
Caveat: I’ve worked for the government for my entire career. It might be different in more sociopathic industries.
