There's an huge amount of entitlement from people coming to the US, as if their presence is a gift and they're owed entry uncontested. For decades at this rate everyone just walked all over US customs and immigration. Now that the US is enforcing immigration laws to similar levels as South Korea, Japan, Israel, Switzerland, Vietnam, etc. people are clutching their pearls. Sorry, refils are no longer free. You're not owed free refils because that's how it use to be.
