Though I'm not for expelling children from decidedly mature European playgrounds, I am in favor of kid-free dining. What is one family's easily ignorable background chatter (ie: kids being kids) is another's theater of the absurd.
I am always in the company of bright minds that have wonderful questions. Most of these questions revolve around the dinner table, and the most commonly asked question is, "How can I tell which is my bread plate?"
While finger bowls may be a thing of the past, they do exist in many private clubs across the country and are still served at some formal dinners, so it's good to know how to use one. Plus, you may want to serve them after some casual dinners yourself.
