Make it clear

As a big fan of Tesco, Anirud always has a question or two about the superstore. We were driving past a Tesco Express (smaller version of Tesco) last week, he asked me if that shop has got a parking space. As I was engrossed on something else, I mumbled a weak 'hmmmm'. Obviously annoyed at my answer, Anirud said loudly: 'appa, clear aa sollu. parking space irukaa, illaya. yes or no sollu' (Appa, say it clearly. Is there a parking space or not? Say, yes or no'.
