Very poor servicing

Bought my lovely Tiger sport here. This went fairly well, except the panniers weren't assembled properly (had to fix them myself in the end as Fowl-up failed to), and a bar end fell off after a couple of hundred miles (obviously not tightened when they installed the heated grips). Oh, and the screen was scratched (I didn't notice this at first, so let it go). First service went smoothly, apart from a missing rubber tank spacer (was there when I took it in). Failers eventually replaced it (after several months and once trying to replace the wrong part). I had hand guards fitted. Checked the bar ends straight after; one was completely loose. Taking the fairing off to replace the spacer, I found a nut missing ( it was there before. The spacer, the nut and the panniers were irritating rather than dangerous, though the loose bar ends were seriously dangerous (the one that fell off did so on the motorway - imagine that going through your windscreen at 90 mph). I suspect the key jobs are done by competent mechanics (some are good), but this level of incompetence is beyond belief. Never again.
