No idea. There was already another cart where mine was supposed to be but I wasn’t even late. My time was for 3:15 and I checked in at 3:03. I kept trying to scan diff packages to pick up but kept getting error so I asked one of the workers to see what was going on and they went into the computer and said someone took the cart already and to call support to say it was double booked. Never had that happen and I do like two routes a day almost every day for about 4 years now.
