"Thirdly, always park in the middle of a parking space with the bike further out towards the traffic lane so that it is clearly visible before anyone does attempt to pull into your spot."
+1 to that,a while ago I parked my bike at some local shops and I do leave it in such a way that's its to the front of the space somewhat and trying to be obvious,id gotten a sandwhich or something and was sitting across the way at a bench and the number of cars that came reeling in and headed straight for the "blank space"between the other cars each side then braking suddenly and being partly turned in had to reverse out was unreal!
hope your bike gets sorted out promptly and quickly with no hassles,id be #$%*ing furious!
