Capn crunch I had the same probem. Your yellow slip is in there until you pull it out. What that means is if any trip comes availble that you are legal to cover you will get it. I put a yellow in to pick up a trip i wanted and forgot to pull it out so once my original trip was over i got another one because the yellow was in there. Once you get what you want from the yellow pull it out or else you will keep getting trips as long as u are legal
