Paying for alcohol: do you, don't you, and getting around it.

[MidwesternSPE]

Hey guys, I was just wondering what your particular chapter's policies are in regards to alcohol at social events? Obviously it's always there, but do you guys purchase it outright from the budget, use a slush fund, etc? Do you pick up bar tabs or have drink specials or do BYOB? Do you hide it as a "room reservation" fee or what? My own chapter has at various times done all these and I'm looking to see what others do.

Thanks!
