Ya THINK?!?!?!
There was a group of Vets who returned to Vietnam for humanitarian work. One who was making his first return trip found that his luggage was delayed. The remainder of the group was motioned through customs & immigration, leaving the new guy alone, nervously waiting for his luggage, with a Vietnamese soldier armed with an AK-47 standing by. One of the American's suitcases was filled with much needed humanitarian supplies that were, nevertheless, considered contra-ban by the Vietnamese government.
Finally the missing suitcases arrived. The American had on a tank-top T-shirt which revealed a large scar on his arm. As he collected his baggage, the Vietnamese soldier asked him if he had been in the war. When he replied, "Yes", the Vietnamese pointed at the scar and asked, "Did you get that in the war?"
When the American replied, "Yes", the Vietnamese told him to go on through, bypassing the dreaded customs inspection.
