I have an approximately 5-6 hour train journey to make soon. I need some ideas of things I can take to eat during the journey without offending my fellow passengers. I can't eat in the morning as I can't bear to look at food before 12, and I can't really eat on arrival as I'm going to a concert and want to get as close to the front as possible so no real time to stop and eat. Although there are some stalls at the place I don't want to be spending time in queues.
Any food/snack ideas would be appreciated. TIA
