The Organic Breath-a-lizer

Being not much of a drinker and definitely not being one to drink and drive, it never occured to me that I would have to submit to a daily or more breathalizer test but that is exactly what has happened.
At first I thought Bitwit was trying to kiss me on the lips. Then it became apparent she was smelling my breath. The moment I arrive at the shop I must submit to the Bitwit Breathalizer to make certain I have not eaten anything she might want and sometimes, I have to submit even more times. She is relentless until she is satisfied I have not cheated on her with a Salmon.
