Sorry for using a bit of a "rerun" - this is from my original comic and due to and uncooperative computer I'm repurposing it for language use.
In Korean there is a word hyuji which literally means "rest". You can add suffixes to make new words, such as hyujishil, a room where one rests, and hyujiso, a rest area (as in one off the highway). However, as I found out, it's important not to confuse hyujishil with hwajangshil, which is where you'll actually find the toilets.
And yes, they sell waffles at rest areas in Korea. I don't know why.
