jump start

A man tries to get into a nightclub with no tie on. The bouncer outside says he has to have a tie, so the man goes back to his car and gets a pair of jump leads and puts them around his neck. He returns to the bouncer and asks if he can come in now. The bouncer says, "Yeah, but don't start anything."
大分昔の話ですが、初めてハワイに行った時に、レストランで入場を断られたことがあります。短パンだったのでそのせいかと思いましたが、理由を聞くと、短パンはＯＫだがビーチサンダルは駄目だと言われました。
