"This is a government job"

A guy goes to the Post Office to apply for a job.
The interviewer asks him,

"Are you allergic to anything?"

He replies, "Yes, caffeine. I can't drink coffee."

"Ok, Have you ever been in the military service?"

"Yes," he says, "I was in Iraq for one tour."

The interviewer says, "That will give you 5 extra points toward employment."

Then he asks, "Are you disabled in any way?"

The guy says, "Yes. A bomb exploded near me and I lost both my testicles."

The interviewer grimaces and then says,

"Okay. You've got enough points for me to hire you right now. Our normal hours are from 8:00 am to 4:00 pm.
You can start tomorrow at 10:00 am, and plan on starting at 10:00 am every day."

The guy is puzzled and asks,

"If the work hours are from 8:00 am to 4:00 PM, why don't you want me here until 10:00 am?"

"This is a government job", the interviewer says.

"For the first two hours, we just stand around drinking coffee and scratching our balls. No point in you coming in for that."
