When I worked for an engineering firm apprentices who were off to site for 6 months as part of their training used to come and see us with a list of basic tools and we would add anything they might need for that particular job. they then went down the local tool shop where we had an account and the guys down there would kit them out.
I was checking one lads list and it had an adjustable spanner on it. I asked him if that was metric or imperial and he said that he didn’t know so I advised him to get one of each.
He came back with two identical tools, I pissed myself laughing until I got the invoice to sign off!
