Most of the time I don't correct people when they spell my name with a Y ("Jenny"). It's pronounced the same and just not worth the time it takes to correct them. But I have friends who get their names BUTCHERED when they place an order at Starbucks. For instance, one of my best friends is named Anika. It's pronounced like Monica but without the M. She always posts pictures of how wrong she gets her name spelled or pronounced. It's pretty funny actually.
Oprah surprisingly said one barista ASKED HOW TO SPELL HER NAME! Who doesn't know how to spell Oprah? (see video above)
Even instagram has over 20,000 (TWENTY THOUSAND!!!) posts under the hashtag #StarbucksNameFails
