Counting on my fingers--the key to unexpected abundance

The waiter delivered two beers to my table. I was seated alone. Similar things happened. Eventually the clues mounted up. "One" in France was not counted on the index finger but on the thumb. Thus putting up the index with the thumb alongside said "two, please." Fascinating, we are different in many unexpected ways. Later a colleague was to demonstrate to me how Chinese can count to ten using a single hand. Impressive.
