I need to know if I messed up

I called a small Italian pizza place with a sit-down restaurant and wait staff, located just five minutes from where I am, to inquire about a job. They told me to come in person to fill out an application, so I rushed over there.

I filled out the application and spoke with the boss, who was really nice. He told me, “You’re doing great,” and mentioned that I was at the top of his list for when a position becomes available because I live so close and have a flexible schedule. He also said, “If you don’t hear from me in a week, give me a call back.”

As I walked outside, I suddenly realized I had been wearing gym shorts.

This was my first job interview. Did I mess it up by wearing shorts?
