Then they came and put down silver cutlery (in a paper bag) and wooden chopsticks in a paper packet. Obviously the less wasteful option would have been the cutlery, but I didn't want anyone (of the restaurant staff I will never see again) to think that I can't use chopsticks... So I opened them!
Then to make matters worse I dropped a piece of sushi in the soya sauce causing a splash the hit the napkins in the holder (which I wasn't planning to use) and the bag from the unused cutlery, and probably causing the staff to draw the conclusion I had been trying to avoid!
