you ever go on the kiddy train ride at disney land?  Calling it now- there will soon be a supermarket for ultra lazy fatties where you ride a little roller coaster super slow, just cruse through all of the isles at like 0.5mph and grab stuff off the shelves as you go- there could even be refreshment stations where they feed you etc and you can just keep riding around in circles through the store till you're done then you press to exit and you branch off down the exit lane
