DRUMMER CAFE

Hi all - been working on reading music, and making great progress, but found a "easy" song thats kinda stumping me on how to write it out... I was listening to Wonderful Tonight by Clapton, and its got 3 quick hits on the high hat in each "step" of the measure, how would that looked written out?  can someone draw up me a really basic picture of just one or two measure of the song for reference?

Thanks
