Question about Thai Food

[Buck]

I have only had it 3 times, all within the last 2 months. I've always heard that you order it on a spiciness scale of 1-10, and that 10 is supposed to be extremely spicy.

First time I ordered I got a 6, and it wasn't spicy at all, then I got an 8, and it barely registered. Last time I went 9 and it still didn't crave my spicy hunger.

I'm going to get a 10 next time, but wtf is up with all the hype?

P.S. I got Pad Thai each time, I don't know if that's just not a spicy dish or what.
