It used to be fairly common. Lookup "Three Martini Lunch." When I was in the oil business several decades ago, it was quite common for 2 or 3 of us to ring up a vendor to take us to lunch where we'd have a couple of beers.

I won't say it's unheard of for myself and my colleagues to have a beer or glass of wine at a work lunch in the tech industry. But it's certainly a rare event though definitely more common when visiting Europe.
