A little OT, but story I was thinking of recently:
Shortly after graduating HS back in the late 90's I got a job at a carwash that was attached to a full service gas station. My job was to spray the cars with a bug-off solution that would help the bug splatter come off the front, windshield and mirrors of the cars that came to the automated carwash. The container I had to use was a small 4 litre pressurized container, with a wand atachment at the end.
I had only been working at the carwash for about 3 or 4 days, when one particular morning I had run out of bug spray. i had called someone at the front to give me a hand as I wasn't sure which container to dispense this bug-off solution from and when nobody came to help me after several requests from a bunch of punk-assed retards, I went into the storage room and started dispensing the closest solution I could find.
Later that day my GF brought her 91 Sprint (Geo metro) to get it washed and I used the same solution on her car, that I had been using all day on numerous other cars. I sprayed her mirrors, windshield, and hood with the solution.
After my shift was done, I met up with my GF and noticed her windshield was VERY blurry...like water had been sprayed on the windshield, but was permanently etched into her windshield.
I scrubbed and scrubbed her windshield trying to get that solution off, but with no luck I had to give up. Turns out I had sprayed her car and several other cars with an industrial grade asphalt cleaner that had also bleached and left marks on the paint that looked like a bottle of bleach had been dumped on the car.
She ended up getting a new windshield out of the deal. There were sooooo many ppl. who got free paint jobs, new windshields etc. all because the staff at the carwash was too lazy to help me out. I quit shortly after this incident...I thought it was pretty funny to be honest, considering it was a big oil company who was paying the bill.
