my dad had glass inbeded in his foot. there was no way to get it out, he could not walk at all. did we get a taxi with blue lights, no. a good strong dining room chair 2 able people (me and my mate) carried dad to my car. trip to the to his doctors, then off to a&e at the doctors request. funny thing is they said "we get a ambulance to take him" we replied no thanks. A&E staff give you funny looks when you take a wheelchair outside and come back in a min later with a bloke in it. Dad had to have a op on his foot to remove the glass, as it was not a easy removal. all done without the help of the boy (and girls) in Green.
