That’s the European thing, most fastfood restaurants in America allow it. The two places in Czech Republic that allow it(KFC and Burger King) have people save their cups and refill them days later so I imagine that kind of theft is why more places don’t have it. Also, European restaurants in general monetize drinks a lot more. In the US it is common for sit-down restaurants to refill your drinks for free, and water is always free (to the point where California passed a law requiring a restaurant asks if you want water before bringing it, to conserve water)
I have never encountered any place (except IKEA) that allows you to refill using those unless you pay a bit extra.
