Do you think he's gone for good?

There's this guy that works through a drive thru. I saw him get into his car once so I know what his car looks like. I go through the drive thru almost every day and I never see him or his car. I thought he quit. Then the other day I went through and I saw his car, it had been like 2 weeks since I saw it. I still didn't see him when I went through though. I figured maybe he had been on vacation and now was back. But today I went through and again his car wasn't there. So now I'm thinking maybe he was picking up his paycheck and maybe ate lunch with some friends he worked with there or something. What do you think, isn't it odd for him to come back from a vacation for one day and than have off again?
