John Mayer was shopping at a Samy’s camera store yesterday when a fan came up and asked to take a picture with him. He said he would for $10. The fan agreed and they took the picture.In the video below you can see the photographer put $10 on the counter and Mayer stuffing the money in his pocket.“I know my value,” ten-dollars-richer Mayer joked. “I know what I’m worth!”What a douch bag. Like he needs $10. Maybe he will use it to fix that stupid haircut of his. Just wishful thinking.
