Anybody knows what
"Anyone found to be regularly misusing the Slovak language in public office now faces a fine of up to $7,000 (£4,300), the equivalent of nearly a year's average pay in Slovakia, reports say"
means?

Because I can understand if you only can be expected to be served in Slovakian, but if you get your doctor fined because he speaks Hungarian with you, because you're much better at Hungarian than Slovakian, then it starts to sound odd.
