I got hired to work space time at a video store. I have been in the work for multiple years now & I love it. The worst day by far was my first night shift. I had been trained & prepared to close the store at midnight for weeks. The first time I did it was a nightmare & it was all because of the oil furnace. The store has an old boiler plan that frequently breaks down, usually the boiler just refuses to heat. If that was the issue, I would have just left & went home, and nope, on my first night shift all by myself the boiler had a major furnace repair. There is piping with a boiler unit. One of the pipes cracked & leaked water all over the floor. The dirty water leaked into the lavatory, storage room & was even on the main floor by the E-I area for the motion pictures. On that shift I had to ring out customers, scrub up the dirty water & find a heating corporation. I needed to get the boiler repaired before I left the store. I could not allow the water to stay on the floor because it would ruin everything. I also could not allow the boiler to continue leaking more & more. I had to use the store emergency fund to spend money for the boiler repair & I had to stay multiple hours later than I was scheduled. It was a single of the worst days of my life. The supervisor was so grateful though. Thankfully, nothing major has happened since then.
