etrang: the "alcoholic" tag is presumably from the link posted by the OP, although I acknowledge that the usual "Daily Mail" caveats should apply.
Vld1977: I fully accept the general point you make about drinkers v alcoholics, but this fellow appears to have a familiarity with drinking ("just a few beers the previous evening"), and his blood alcohol level as reported would appear to indicate greater consumption than just a few sips taking him to a different state of mind, particularly as a number of hours had passed between his admitted consumption and his test. A few units would have metabolised over that time.
