A quickie. Should you find yourself in the sort of joint where they provide chopsticks in paper wrappers, and the table setting lacks the requisite elegant porcelain chopsticks rest as found in the more upmarket establishments, you can give your table a touch of class (I won't say which one) as well as amuse your dining companions for entire seconds with this neat little trick.
Place your chopsticks vertically on the table with the open end of the wrapper uppermost. Hold the top of the paper and pull down the length of the chopsticks so that you end up with a ruffle of paper.
Place ruffle of paper on table, rest chopsticks on it, admire – and prepare to be admired.
