Well...it sounds like everyone was down to get good and messed up here given the amount of booze, and different types of booze presented in your case. My ruling is you're probably gonna be in the clear. I remember getting good and fucked up at a few holiday parties at my old job. I was witness to one co-worker puking in my boss's flower garden off the front porch lol. Walking out the front door to peace out, "Dave" was just hurling into that flower bed full boar and just hap-hazardly tried to waive bye to me mid puke stream lol. Anyway he was very much not fired.
