Shaking Hands and Hand Sanitizer

ERIDC told me this story about a recent interview she had:

She goes to meet the manager at a small company for a job interview.  They say hi and shake hands.  They sit down in this woman's office.  As they chat, the manager discreetly gets some hand sanitizer and proceeds to rub the sanitizer through while keeping her hands under her desk. 

I guess that's not so weird in the season of swine flu.  People are super-paranoid and that's OK.  I just can't help but wonder what if it was reversed?  What if the job applicant goes for the hand sanitizer right after shaking hands with the manager?  I'm guessing that would looked upon poorly by the manager.  Or even worse, what if one is white and one is black?  Especially, if the one using the hand sanitizer is old and white, I feel like that could be construed as racism. 

So I guess my general advice for applicants is don't use hand sanitizer in front of anyone that's evaluating you for a job.  Go to the bathroom first.  I guess for interviewers, I would suggest using hand sanitizer out in the open and not trying to hide it; maybe give some line about swine flu.  Otherwise, it just looks weird.
