It was a Tuesday, this London bank, one of the biggest, was full of clients coming to deposit their payroll. A compact crowd occupied the place. Vincent, a new clerk, was trying to get through this herd of wild beasts coming to claim their weekly pay. He was going to get some documents in the adjacent room, swimming against the current in turbulent waters when those words got in his left ear.
“I’m sorry sir, but your check is fake”

He promptly turned left in the cashier’s direction, fake money was his speciality.
