How to do polite Google searches

Google can boast that it has found its most polite user. May Ashworth, an 86-year-old grandmother from Great Britain, unintentionally uses "please"/"thank you" when searching for dance on Google.

Ben Eckersley, the grandmother's grandson, came to visit his grandmother one day, and while using her laptop, he noticed an open tab with Google search.

"Please convert these roman numerals MCMXCVIII thank you", was the search typed by the grandmother, followed by the answer "1998". 

The dancer's grandson, very amused, shared the picture he took with his grandmother's search engine, collecting almost 30.000 shares.

Both Google from Great Britain and the main Google responded to the nephew and grandmother on their Twitter accounts.
