The victim told police that, not only did the gunmen give him his license, they also handed him all of his credit cards before running off.
You can file this in the "Could Have Gone Much Worse" department -- and, for the record, attempting to bargain with a gunman is a questionable move. If nothing else, however, it makes for an excellent yarn. We still tell a story about an event that happened years ago to a pal on the New York City subways. Mugged at knifepoint in the wee hours, he angrily told the assailant "you could at least leave me a token so I can get home." The mugger laughed and said "I like your style, kid," before flipping him a token.
If years of barroom storytelling outweigh the possibility of violence from a well-armed and potentially deranged person -- well, bargain away.
