Re: Postmen.
Next time I see one I will ask, and report back
, meanwhile, here is my theory.
In the hot weather, it is an obvious choice, an attempt to keep cool, in the cold wet weather, it is easy to keep the top of the torso warm and dry with a good coat, but, the precipitation naturally falls, and soaks the trouser, which can be protected, but at great cumbersome cost, this must be uncomfortable, so it is just easier to dry the legs with a towel, when back at the van (and change the socks)
