Was I being reasonable? Was I out of line in this situation?

I am 33 years old. I went to an interview for a minimum wage job at a new Burger King (yeah, times are that hard here in Florida) and I drove 10 miles in the pouring rain to get there on time. I was on time- 2:30 sharp. Then as I approached the temporary trailer where the guy is doing the hiring for the new store, a sign told all interviewees to report to another city 12 miles away for the interview. I was angry but I still made the trip in the pouring rain. Then when I finally got to the other Burger King 12 miles away I sat down at the manager's little table and was ready for the interview. He told me to sit somewhere else and wait for him to interview other people. I told him I was leaving and I was upset that he didn't at least give me a call before I travelled to the other location in the pouring rain. He didn't say anything but an insincere apology and I told him he was being disrespectful about the whole thing and then I left. Was I out of line to stand up for myself? Was I out of line by leaving? I was seriously pissed. I mean, I was fuming. He was late, he told me to wait, he didn't call me, etc. I really wanted to punch the MF'er but I left quietly.
