seriously though like ventis day to day alcohol intake depends almost entirely on the people of mondstadt paying him for his performances in alcohol because literally no one will serve him
the one time he's even been drunk on screen was jeans story quest and that was...
thirty seven glasses in and even then he's only just gotten tipsy
So Venti's not even able to drink at the Angels Share unless Dilucs tending the bar (which he rarely does, this is why Charles barely has days off). This is unless Diluc has specifically told Charles he can serve Venti (which I doubt, but it's a possibility). And even if he does get drinks he remarks that on a regular basis he does not have enough mora to pay for enough drinks to even get him tipsy.
In conclusion Venti's not going to be coming home completely hammered on a day to day basis, or at all like regularly so like calm down people. of course he shouldn't drink so much anyway because you know alcohol smells horrible but i digress.
