If I personally saw it? I'd give it a thumbs up and a smile.
Now, if a slightly more sane person were to see it, then who knows. The one of the better things about tails, though, is that depending on how you approach someone, they can't see it until you turn around to leave. The benefit of this is they get a chance to meet you, find you're a smart and nice person, and nothing wrong with you. Helps as a set up.
Plus, secretaries are usually behind those big desks and sitting down, so no one would see it and be spooked (customers, at least). Little kids would probably love it, which would be great for calming them down in the waiting room (which is always a scary place).
