It's not just tech companies lol. It's funny, the place we would have meetings--when it was a lot of people--was 50% off for the company. It was a nice cantina. Let's just say my beer mug was a jug and I didn't have to pay for it lol. >_> one time I was the designated driver sigh. Good thing it was a minute drive and then we would all drink more at the bosses house. Even when I worked in education, no one gave me shit coming in smelling of booze; one day I had to call off after reading my students file. No one blamed me for getting shitfaced after reading that.

You're not the only one, I've been with quite a few startups and before that I worked with VC's to help get new portfolio companies rolling with IT. Never have a seen it, I've only heard of it.
