Was that racist?

I went to Whole Foods for lunch. The line system works like this: there are three lines using a pool of cashiers. There is a TV with three sections on it, corresponding to each line. When a number comes up and the voice tells you "Line X" you go to line X.

There was a Jewish man in the line next to me (he was even buying matzo). They call line 1 for him and he walks towards it. The cashier is Muslim, she's wearing a hijab. He walks closer, they call a line number for me, line 6. He turns and runs to lane 6. I walk to lane 1 and look at the cashier; she looks at me and gives me an awkward smile. I laugh. What else could I do?
