Well, let me start this string by listing the stupidest thing I ever did in this business. ( also pretty funny, in retrospect ! ) About 4 years ago, I was in a customers back yard line trimming. This was gthe 2nd season that I have been taking care of this lawn . This year, they put up a small pool for the kids. Well, it's July, and the pool has been up for 2 months , and I have been leary about line triming too close, but it's starting to look kinda shabby around the pool. You know what type of pool this is. No filter, 24" x 12', available at every K-mart or Walmart ( or so I thought ) , has a vinyl bottom, and metal sides. Well, I was line trimming , got too close, and nicked the bottom , that was protruding out from under the sides.WHOOSH, I immediately had about 800 gallons running between my legs, heading down hill. As I nicked the bottom, the side simultaneously split, allowing ALL the water to exit. NOW. As I stood there, my feet freshly washed, thinking " you dumb^%$#^%$&*$^&*%", I realized that I just bought a pool. I went to front door, and spoke to homeowner, we went down in basement to get empty box, so that I could replace the pool. I apologized profusely, and she was fine, as long as I agreed to replace pool. Did you know, that by mid-July, you can't buy pools at Wal-mart ? they already have fall stuff out !! I never did find a pool( even after I phoned the MFG ) I ended up eating their bill for that month ! They were happy with that , but I guess the kids were'nt too happy with me !! I did keep as customer, until they moved out of area, so I didn't lose them . As I look back on, it was pretty funny to see all the water go between my legs, soaking me almost up to my knees ! Just glad nothing other than my pride got hurt ! NOW, anybody else want to confess their stupidity , for all to read ( and learn from ) ???
