This behavior of someone taking offense to you not wanting to drink with them is something I've seen before. What's particularly infuriating about it is that you shouldn't need any particular reason not to drink. Whether it's because you're a recovering alcoholic, or you just don't feel like it, a simple "No thank you" should be enough.

On a side note, I remember having a discussion with a coworker about after work drinks. She noted how sometimes people would be willing to stay and work more if they knew they were going out for drinks afterwards. I imagine the way alcohol can relive stress with immediacy can lead one to willingly work in more harsh conditions. Hell, I've stood extremely late several times just because I knew I can join up with friends later for a drink.
