For me, it has nothing to do with past performance. If people here are seriously suggesting that they could go into work and meet clients/public and give the impression rightly or wrongly that you were on the tear the night before and there wouldn't be consequences, then we have a serious attitude problem towards alcohol. I go out during the week. Sometimes I drink too much. However, I am always aware if I have something on the following morning and act accordingly. I am not a child. The least I would do is get someone to cover for me if I did go overboard. I certainly wouldn't represent my company sounding like he did. Having said that, he has apologised so it us time to move on.
It is getting to the stage now that people who did not see the interview will have an image of him with his shirt hanging out and slurring through the whole interview. His quality of speech is never great and his vocals are usually nasally so this has all been completely blown out of proportion. Can anyone say with any certainty that he was in a bad state? I saw the interview and it didn't bother me.
