Better in his mouth than nose.

If I were a famed (or unfamed) chef this would not be the promotional photo I would choose. But that's me. I am not Alan Wong who happens to make the most delicious Loco Moco. Chefs are clearly a different breed than Hygiene Hunters. Walking around with a finger in my mouth -- particularly if it was someone else's -- would be disastrous to my brand. Onward. While eating at Alan Wong's two restaurants (not at the same time) I never once saw Alan do the above. Perhaps because he wasn't there.
