Interviewer said “I’ll call you to set up a couple things”

I had a job interview today and it seemed to go very well. I interviewed with a manager and the owner of the store. The owner asked me about my hours and we seemed to get a long really great. During the interview the owner kept saying “is this something you’re interested in” and even complimented me on some of my answers to her questions. Also the manager said to the owner in front of me that she really liked me. When the interview was over the owner said “I’ll call you later today to set up a couple of things.”

My interview was at 12:30 pm and it’s now almost 6:30 pm. They closed at 6 and still no call. I left feeling great about the interview but now I’m getting a little worried and second guessing how well I thought it went.

When I left it was a little awkward! I didn’t get to say thank you like I should have because customers came in and the manager and owner went to deal with them immediately after the interview. Am I over thinking the situation?
