aaaaaaaaaaaaaaaarrrrrrrrrrrrrrggggggggggggggghhhhhhhhhhhhhhhhhhhhhhhhh!!
what do you want done?
should she get free shopping? a few grand? should someone in the shop be sacked? should they change the layout to the shop entrance? construct a device to ensure rain never falls near their store?
Nothing serious has happened - or if it has, your family have shown a very lax attitude in getting her proper medical attention, maybe she should sue you for spending time on the internet seeing what you can get instead of looking after her!
But instead, feed the compensation culture, give the vulture ambulance chasers their pot of gold, drive up insurance claims, make life harder for businesses, drive up costs for consumers and all for a few quid when no harm was actually done.
Even if there WAS a spillage, if the shop was in the process of doing something about it, you'd have next to no case as you'd have to prove they were negligent in addressing the spill, but i think it's more likely the spillage was just a puddle carried in on the feet of otehr shoppers (sorry to doubt your dads word on this)
I hope your mum has nothing hurt more thana wee bit of pride at having fallen in public, but i just wish people wouldnt suddenly blame the world and demand compensation.
It's one of the many things of modern society that utterly depresses me.
