If someone spat on the ground in front of you as you walked by would you say something ?

I once had a guy get out of his car and scream at me. I had the window closed and I kept it closed while smirking sarcastically and making faces at him. ((Aren't I evil))....So, he spits in my face....and it lands on the window. I pretended to lick it off the window,....making him even more furious! Eventually he left.
