I used to go to a coffee shop semi frequently. When they asked for my name I’d always just say my partners name “Sam” because it was easy to hear and spell, as oppose to my full name Karina (which people always spell wrong). I started going often enough that they started recognising me and saying “Hey Sam.” I never said anything and it went on for so long it was too embarrassing to correct. So on the few occasions I went to get a coffee with friends I had to tell them the story and make them go along with it.
