A customer asked one of our techs to save the grease he scrapped from their system, she left a huge pot for him to put it in. He felt the need to call me at 3:00 am and ask if that was ok and of course, I said no because he had sprayed chemical! She was upset the next morning when I explained to her why we could not do that. I asked her what she wanted it for and she said it was not my business. In hindsight, I probably did not want to know. Needless to say, I would never eat there.
