Drink Driving

I was driving on a highway in Singapore and a random roadblock was spotted there.

Prior to driving past, I dropped a drunk friend.

As I drove slowly for my turn to pass, I decided to do this.

Officer: Sir, random check. (Sniffed) sir please park to the side.

Me: OK.

Officer: sir, were you drinking before you drove?

Me: Yes I was.

Officer: How much did you drink?

Me: 2 jugs

Officer: Sir please step out of the car and walk on this straight line.

(I passed. Breathalyser Passed. Officer was puzzled.) Officer: what did you drink?

Me: Orange juice sir. You didn’t ask what I drank.
