>>2634009If you're just going bike camping for a while you should be able to bring the food you need, but if you're talking about bike-packing you do what other people do, chain up the bike outside the store and shop quickly or take your bags inside with you. If it is a store that won't let you carry bags in you can always ask an employee to watch them for you but then you're trusting someone still with your cargo. No perfect solution. I'd recommend getting a telescoping fishing pole to help with food unless you've got to travel at a nearly constant pace besides camping at night.
