OMG, I'm calling PETA!!!! I wouldn't worry about it.
My last account of the day yesterday. My customer, a retired senior citizen but not ancient or anything, comes out as she always does to move her car. I'm talking to her about her lawn and meant to say Crab Grass but said Crab Ass instead, at which point I jokingly apologized for insulting her. We chatted a bit more and then as she was walking to her back door to go back inside I said "see you in a few weeks Crab Ass." I just couldn't resist, LOL. Mind you this is my 11th season servicing her lawn and we know each other pretty well.
