I certainly hope they're charging decently, then.  Even if it took just an hour, .185 (about 12 and fifty right now) per logo isn't exactly much.  When businesses are demanding logos left and right to fill up an entire day's worth of work, every day, non-stop, then it's a nice rate.  But once every now and then for a little extra on the side isn't a "rip-off."  It's not even part-time.

Further: those logos aren't very marketable.  They're all flash.  They look great artistically, but businesses (aside from a tattoo parlor maybe) aren't generally looking for logos like that.  I'm assuming they're using a 3D text tool and adding cool effects, which, as you say, doesn't take much time, which also implies it doesn't take much thought or effort into what the business actually needs for a logo.  Pick a font, add the effects, done.
