Re: Nail in my tyre
could just be bad luck - is the car park a bit crappy?
I had a run of nails/screws/old drill bits like that one year. Keep a spare and check your tyres regularly. Try not to drive over the dusty bits where chevrons are on the motorway. Only use the hard shoulder when you have to and check your tyres afterwards as those places end up full of all sorts of crap.
Are they all the same type of nails (like the very wide, flat headed roofing nails)?
Last time the roof was done at our shop there were nails bloody everywhere. We ended up brushing the car park off then whizzing over it with a sea magnet to pick up any missed ones.
Someone with an axe to grind is much more likely to simply slash your tyres or pull off your valves, or do all 4 at once.
