Customers and certain stations on the green side will give you one to three contamination points when you interact with them. (The math needs to be a little fancier to avoid taking any away by accident, but mostly it works as expected.) There's two 'score'-type values tracked in the top right- each customer gives you a set amount of money once you complete their order cycle, but pink-side customers give you bonus points in the other-category-i-forgot-what-i-named-it depending on how many times you interacted with them while contaminated. It doesn't do much beyond that yet, eventually in theory you'd be able to like. unlock shit
