It depends on the size of the company in relation to the store. And yep, franchised means the owner has got to pay for improvements outside of the franchise contract. But still, our scales are accurate to 0.05g, which is overkill for food, and “only” around 7-10k per, if you only have to be accurate to 1g, they shouldn’t be more than 1-2k.
About the example by OTP of his issue that they remove the scales next to the coffee, in relation to being the store manager, considering how little commercial scales cost, while also acknowledging that different stores (franchised or not, size of company vs size of the store) can impact the managers ability to provide such improvements to their customers.
