1st you need to add something like a skip day button for people that got so much money that it become trivial they just want to unlock scene by scene
2nd the food and drink drag to customer getting real repetitive and boring real quick i would suggest to just let it auto check mark watever the customer need as long as you have them in stock and a maid is there to "assist", i have a feeling you going to add in some kind of shop expansion so we wont be dealing with just 4 chairs 3 maids problem and customer constantly getting mad so that would eliminate that bit of head ache, may be switch out the food and drink bar for something "fun".
3rd may be add in option to upgrade the shop into a bar and we can have our main guy be bartender and maid getting frisky stuff 😉
