A conditional "-(으)면" plus 시키다, which has two everyday senses and both are here. Ordering food: I'll order it if they have it, I can order the gukbap for you, you can order pork rind at a samgyeopsal place. And making someone do something: if you were going to react like that, you shouldn't have made me. Two lines are the set phrase 시키면 시키는 대로, "do exactly as you're told", which uses both senses of the verb in one breath.
