They called him by my last name

Liz

So long story short my SO and I had to get a new phone plan. Middle of the day nobody else in the store we were joking and have a general good time with the staff members helping us. I gave her my ID to set up the account and later she asked him if he wanted the caller to bring up his name or just the number. He said yeah name and number is cool. “Ok *typing* Jason (my last name).” Oh no, his last name is (different last name). “Oh sorry you guys are so familiar with each other i thought you were married.” Not gonna lie I kinda liked the sound of him having my last name.
