Sockless highflyer

We spent Christmas at Hilton hotel in Stockholm and during breakfast I found a co-worker who also did the same in the same hotel. What is the chance of that happening!?
Anyway, sitting close to us during the breakfast was a man who had no socks in his loafers/shoes. Mind you that it is winter and Christmas. He is discussing stocks and shares with his friend. He said that he needed to gas on stocks (buy more) at the SEB Bank. It was a bit funny as he was sockless...
