The dining car service as been the same. They did not serve dessert with lunch either day. But we had dessert with dinner last night. The crew explained there was not enough dessert on board for lunch and dinner.
I seem to recall being on a train with you (possibly several years ago on the California Zephyr?) when there was only one chocolate dessert remaining and we both wanted it. Am I remembering correctly? Since you are way younger than I am, I will defer to your memory. Is it possible that on that train, they ran out of Diet Pepsi? I do recall having a serious caffeine craving and getting the last Diet Pepsi (much to Kevin's disappointment). That was my last Diet Pepsi - I no longer drink any soda.
