Encounters with racism?

It was about 2 years ago. I was on the bus going to college, and some asian students got on the bus. By this time there were only two seats remaining on the bus, and they were the ones next to me. Now the first asian student took one look at me, and urged his friend to sit next to me. He did, but as far away as possible from as he could get, they were practically sat atop one another.
When another two seats became available, they soon jumped out of their seats and moved onto the empty ones. It's as if they thought that they would catch something from me if they had to sit next to me.
I felt really uncomfortable and out of place on the bus while they were on even though I had done nothing wrong.
