Wait to see what (s)he orders (offer to buy him a drink?) before buying alcohol. If (s)he puts you on the spot, order a diet Coke or something. [/I]
Years ago I had a Director who did the same, one time a candidate asked me what should he do, so I just said be yourself.
He ordered a pint (which was fine) and a whisky chaser…
He did get the job, but I also discovered about a year in that he was a raving alcoholic – so he was given to me to manage, as I have a particularly handy approach to managing ‘difficult’ characters.
He also spoke about a dozen languages and would never fly anywhere, so would spend his weekends traveling by train across Europe (I used him mainly in the East).
