Untalented plumber

Been frequenting the hardware shop alot since the last 2 days (6 visits in 2 days to be exact) and the only reason for that is my not enough pvc pipe tubing/ wrong connection piece and forgot to buy a thing or two (I must be the tokey's favourite if not the most weird customer...keep popping up at his shop every 20 mins!!) All of these indicated 1 thing...thank God I'm not you neighbourhood plumber, if not the pipe leakage will still be a problem after 2 days! *Going back to finish up the plumbing work right now
