How does a layman kick?

I need to find some good self defense applications against kicks.

While Karate has a lot to offer for defense by using arms, legs, throws, I am especially interested in how a layman attacker would kick and instruct my partner to do it this way instead of using the well trained e.g. Mae-Geri movements because I think that misses the point under these circumstances.

I think most people will kick to the shin or groin like hitting a football, using a swinging or keage motion or pull up a knee and stomp. Is that a proper assumption?

To make things worse I need to find an application against kick combinations. I learned e.g. Mae-Geri -> Mawashi-Geri -> Ushiro-Geri in one sequence, but I highly doubt some random drunk ruffian who just dislikes my face would ever do that. Suggestions for something plain simple? The only thing I can come up with at the moment is that the opponent tries to stomp my foot several times and misses because I move.
