I may be making this up, but aren't there some rather strict rules about surgeons and alcohol? It may make them more likely to just take the day off.

I'd guess that few surgeons start boozing at breakfast on their birthday or have a lunchtime drinking session to celebrate. But are more likely to be rushing off to have a party than actually be impaired.

I more thought you might need to request the day off to avoid being on call, surgeons have very unstable hours.
