1 thing that always bugs me with MC's that can pause time for food and store it as long as they want and it stays the same is that they never precook much, like you could spend a day or 2 just cooking and then store it in your subspace, (or pay someone to cook it) that way if you run into an issue you have hot and ready food at any point, its not like he is short on money and can't afford it, like he is not short on space, money or time, yes lets just keep all the money in the bank, what if there is a food shortage? can you eat that money? no you can't, what if you need to go on the run because a corrupt noble took a liking to your slave? or any number of things, he could easily store a years worth of food for a 'rainy day' sure he did buy like a months worth but why not buy more if its not going to go bad.
