...I lied. Granted, I was working at the time, and didn't want to deal with any potential fallout while working (so you could claim duress played a part), whereas the other chances I've had were during "down-time".
Butstill, I actively lied about why.
Okay, so technically speaking, it wasn't a lie. I told them that, "I hated it", and then elaborated, "hated the beard". A half-truth, but one which was delivered in a deliberately rather than accidentally misleading way turns it from being a half-truth into a lie if by nothing else than omission.
I'm such a coward. It really, really sickens me. I should be stronger than that, to have the courage to say the truth.
But I don't.
