Not to all Brits! Many posties wear shorts all year round even though they are not supposed to for ‘elf & safety reasons. But there is nothing worse than soaking wet long trousers. Well all trousers really.
I knew one who took a short cut across a snow covered front garden on a delivery round he didn’t know. Only it wasn’t a garden – it was a 3’ deep ornamental pond! Nearly froze his balls off!
