That is what I thought, thanks
I'm a little surprised about the ランチ thing though. I learned it a long time ago, but my book likes to obsessively use katakana words in place of Japanese words (I guess to make the material easier or something) so I always see things like ミルク over 牛乳 etc. I thought they were just doing the same thing for ランチ but I guess I was wrong.
