OK - seems to be subjective as always...
Just out of interest, does "drunk" in this context mean "blood -alcohol content over a certain level", or "appears to possibly be under the influence"?
For the record, I generally do not drink. Apart from special events, where I redline at about 3-4 units.
As a general rule, ought I leave it 12 hours after any alcohol at all before a flight? Follow the same rules as the people up front?
