Don't hate me 'cause I'm beautiful

Today holds the record for most askings of this question per time worked, 3 times in 3 hours:
"How are you so skinny when you work HERE?"

The answer I give:
"HA HA HA Oh well you know... Sure I can't make that half a dozen? There's no tax."

The answer I want to give:
"Because I don't stuff my face... You maybe want to rethink that extra butter tart?"

Ah, the cheerful bakery life.
