That usually leaves them quiet.
This.
It's like if my boss was going to jump off a cliff... and I didn't participate, would I be questioning my choice to not jump off a cliff? Sure I will go watch them jump off a cliff if it makes me part of their crowd, but being part of their crowd only goes so far until it puts me in danger.
If they drink, fine. if your employment is based on whether you drink or not you need to find a different employer.
I found no one cared if I drank or not, as long as I didn't condone them for drinking. I see fools jumping off the cliff every day, it doesn't mean I have to join them in order to work with them. If my work isn't good enough than again, I need to seek other employment.
