> I find it hard to believe that any company would allow daytime drinking.

Allow? In some cultures a beer or glass of wine at lunch is perfectly normal. There is also a big difference between having a beer and downing a 6-pack.

I personally would avoid a beer at lunch because it makes me tired, but I wouldn't think much of it if someone had a beer with their lunch.

Beer at lunch is fine with me. Beer at the keyboard is where things gets weird.

(Unless it's friday evening and your are working hard while everyone else is at the special beer break.)

Where I work we have beer on tap. People are free to drink whenever and the occasional person will grab a beer with their lunch but peer pressure and not wanting to be drunk while at work means most people won't drink during work hours and it's used mostly after-hours or on weekends.

If it ever became a problem or someone got shitfaced I'm sure we'd see restrictions put into place quite quickly.
