2 FBOs were assigned. After deadheading (no passengers), we were to pick up 4 and depart. Our tripsheet said to land at one FBO, and take off (depart) from another. We were left to figure out which FBO the pax were being staged. The second FBO turns out was a managerial error. When it gets pointed out that management makes a mistike, it's no big deal. But if we ended up at the FBO the pax weren't at, guess who would have gotten blamed. Curiosity satisfied ?
