Depends on the people. There aren’t any strict rules. Some people won’t, some will. Some might even end up in bed right after. As long as everyone involved is comfortable with it, it’s fine.
If you aren’t comfortable with drinking on a first date, then don’t. If like me you never drink alcohol, then don’t.
Also depends on the alcohol. Large difference between wine and vodka.
But I haven’t ever dated either, so… Personally I can’t imagine any date that involves any drinks and food. Coffee, I don’t do that either. Tea? Down in one go. Water? Awkward, and also down in one go. Food? Can’t focus on anything else, gotta finish first.
Look at the bottom with server count. Likely something screwed up there, and when those instances were suddenly returned, the user count was added back before being subtracted when they disappeared from the data.
