It was one of those slang terms for ‘someone you wouldn’t trust to buy a stamp at the Post Office’ (I’m quoting a former colleague – who typically followed the observation by: ‘Oh my God, he is such a tool!’)
But, this time, I have a different perspective on ‘Tools’. Take a look (specially for fellow-cyclists):

This is from the special cyclists’ garage in the Parador Hotel I stayed in last night.
How amazing is that?! (They also had a foot pump, gloves and other supplies).
In the 11 years’ cycling long distance trips (all over the world) I have never seen such a cyclist-friendly facility (and – no charge!)
Well done Paradores Hotels!
