Dave, the legal speed limit for a bus on stage carriage service (one with a number on da front who keeps pickin up punters) is 30mph. But I didnt tell you that, OK? If he is doing 50 he is obviously late for his lunch break or he is on his last trip before knocking off :-)
I always check that car next to me has enough room to open his door in a car park, but am sometimes mortified on returning to find that the car has gone, as has the one the other side and a few others, to be replaced by cars taking up more room. I am left parked so that nothing can park beside me at all. It werent like that when I left it, honest it werent, hofficer!
