Am I right or wrong?

A man arrives at the repair shop to pick-up his watch. 

Clerk: “I haven’t finished repairing it yet. just give me a few more minutes. 

Man: “Sure, no problem.” 

The man goes and stands right next to the clerk, who notices him but continues working. After a while, he can’t take it anymore. 

Clerk: “Why are you sticking so close to me?” 

Man: “I’m only doing what the sign outside your door says.” 

Clerk: “And what is that, may I ask?” 

Man: “It says, ‘Watch Repairs.'”
