I recently re-did my kitchen floor with 1' square peel-and-stick vinyl tiles. After buying four boxes (30 tiles each at $45 a pop), I ended up exactly one tile short. I was sorely tempted to go back to Home Despot and slip one tile out of a box - obviously people do this a lot there since there are always open boxes in the tile section. In the end I just pieced the last tile out of scrap bits, in a spot where it really wasn't obvious. I don't need a fucking shoplifting charge at this stage of my life.
