Exactly.

My last trip had 3 of these, after each layover we never left from the airport from where we arrived. HOU-IAH, SJC-SFO, and SFO-SJC. If you include the 40 minutes we had to wait for the SJC-SFO van (we'll be there in 5 minutes, really...) I had over 4 hours of unpaid van time on my last trip. SUCK! Don't get me wrong; I'm on RES and didn't make guarantee so I didn't lose a dime, but it still sucked seeing that 13:30 layover turn into 10:50. As a line holder that's real money that just disappears into the ether.
