Last week, I had to have our a/c diagnosed. Although both of us were still experiencing Winter time weather in our area, it was nothing to be in the twenties 1 week, & the next week both of us were having summer-like temperatures. I made the appointment & was surprised that they were sending an Heating & Air Conditioning professional to our cabin the following Sunday day. The Heating & Air Conditioning tech arrived precisely at 8AM. I was up, dressed & had already finished our breakfast before she arrived. I watched as she got out of the repair van, & swore she was staggering. She seemed to not be functioning & she should be. I wondered if she had some kind of medical problem, however then she disappeared from sight when she got up on the porch. I was shocked to see her blood shot eyes & the faint smell of a substance around her lady. I didn’t want to let him in the house, so I pointed to the a/c machine around the corner. She looked at myself and others a bit oddly, however she headed back to the AC unit. I watched out the window as she began to look around. I wasn’t sure what she was looking for, until I saw him pull something out of her pocket & puff on it. I assumed it had to be an electronic cigarette, however that wouldn’t make her eyes glassy. Before I provided it much thought, I called the Heating & Air Conditioning corporation & told them our suspicions. I didn’t mean to get him fired, however I swore the man was on drugs, & I was right.
