An Inquisitive Riley

Question

I'm taking a quick break from my new story riddle, and I decided to craft another simple Riley for you guys. Good luck to all of you!

Mix up the prefix, using quail equals bird; but don't move too fast, or you'll scare off the third.

Ask for the infix, from the guy down the street; he's the one standing, no shoes on his feet.

Keep up the good work, the suffix you seek; rationalization your enemy, no wait, that's just me.

Remember this warning, I've told you before; the answers are here, but you're searching for more.

Explain the title.

Hint: Since this is another one that seems to be proving difficult, here's a hint:

Acrostic

MAKR is an anagram of MARK. A question mark is something used by inquisitive people when writing a question.

Mix up the prefix, using quail equals bird; but don't move too fast, or you'll scare off the third.

Ok, I think this creates que by taking the first two letter of quail and the first letter of equals. I think "scare off the third" means that the e in "que" is separated a bit from the rest of the prefix.

Ask for the infix, from the guy down the street; he's the one standing, no shoes on his feet.

This line has two words that start with st (standing and street) I think there might be more to this hint though...

Keep up the good work, the suffix you seek; rationalization your enemy, no wait, that's just me.

the word "rationalization" has the letters tion twice in it.

The letters are all in the puzzle however once you get the answer you're left with a question which is searching for more information.
