Haulers can't pewpew?

I managed to undock in the wrong ship and make it to the site I was going to do. I went to lock on an NPC and shoot it when I realized that I was in my hauler and had no gun or any pewpew capabilities.

*sigh*

I was punished for the huge attention lapse. The site despawned while I warped out and came back to it. Poor me.

Later, I found another Radar and a Mag site as well. While I had almost finished the Radar one of the larger more vicious PvP corps jumped into system. Because I was watching my dscan I was able to catch their scout, who was a cloaky falcon right before they came in. Once they decided to hang around for a bit I decided to pull my drones and leave my site. I had pulled one object out of it so the entire site was not a loss. Thankfully, when I came back it was still there and I managed to crack a few more goodies out of the cans. All told, it is about 20 mil worth of stuff for the hour it took me to find and pull it. Not bad. It'd be faster if I was better at killing the rats. I also keep finding angel chemical labs but I cant tank them. Its frustrating.

The second site was meh. At least there was stuff in it. As I finished it up, said corp came back through the system. I finished and docked. I need to go to work and I'm just not in the mood to play with them.

To top off my day, the contract I had up for the goodies dropped by the faction spawn the other day sold. 165mil for zero effort on my part. It was not even a large rat that dropped the shiny bit of shiny.
