In Sweden you can only sue in civil cases where there's a real disagreement, not because someone spilled coffee on you. Not sure if it would be applicable in this case though.
We often hear about the crazy lawsuit culture in US anyway and how insane it is. Whether that is true or not I don't know.
Throwing hot coffee over someone would that not be covered then ?
But tort law does exist, right? So if somebody purposefully spills boiling hot coffee over you, you will be able to sue them. The claims are just less outrageous than in the US because there are no punitive damages for example.
