I had lunch at Fuji today - a basic sushi and sashimi meal. I paid the bill and left to shop, and in about 10 minutes began to cramp badly and need to visit a rest room, symptoms I and others who eat raw fish might recognize. Fuji was around the corner, so I went back in, heading down the stairs to the rest rooms. A cook was coming in at the time, and when he saw me going down he informed me that the restrooms were not public. I replied that I had just dined there a few minutes ago, but was not feeling sick. He repeated his warning, a little more threatening. I replied that I was sick from their food and has been in the restaurant a few minutes earlier, and headed down to the basement where their restrooms are. While I was waiting, very uncomfortable, for someone to exit the toilet area of the men?s room another person came down and very rudely ordered me to leave, saying repeatedly ?public rest room outside?. I replied, again, that I had eaten there a few minutes before and was now getting sick. This man grew increasingly belligerent and threatening, crowding me in the little restroom. I stumbled outside and walked 50 very uncomfortable yards to the cold, damp public restroom, where I had a moment that victims of similar circumstances will identify with. It was not my last such moment today.
