The foreman on a large worksite noticed a new labourer one day and barked at him:
“What’s your name?”
“John.” The new bloke replied.
The Forman scowled.
“Look, I don’t know what kind of wishy-washy worksite you were on before, but I don’t call anyone by their first name. It’s weak and wastes time. I call my employees by their last name only Smith, Jones, Baker, that’s all. If I want a job done, I yell, Baker, get this or Jones, do that. Now that we have that straight, what’s your last name?”
