Personally I don't like the stuff, but I was wondering what the implications would be?
Obviously it's non-alcoholic so not against company policy and doesn't break any rules. But it smells like beer, looks like beer (bad if any clients are visiting) and might raise eyebrows?
Is the fact that it can be mistaken for an unsuitable product cause for it to become an unsuitable product?
Oh how philosophical...
UPDATE: I'm in the UK and the non-alcoholic beer here is advertised as being 0.03% - 0.05% alcohol (I checked the ones in my local supermarket). There is one marketed as 0.0% but I think they're rounding down to one decimal place. However, as the answers have pointed out, the fact that there is any alcohol at all probably makes this question redundant.
