More stereotyping than racism, with some good old-fashioned sexism thrown in at the end. The last guy, knows she's stealing the bike and offers to help her steal it.
It's all a matter of perception. We pre-judge based upon appearances. In my younger days, I got called out to haul off a car that was blocking a manufacturing facility's dumpster. Someone in the apartments across the alley had parked there. The man that called was very nice and apologetic and offered to pay me just to move it out of the way, rather than impounding it. He said he had knocked on all the doors, and not a single person was home. About the time I started to tow the car a woman came running out to retrieve it. The guy, one of the nicest people I met in that line of work, could not understand why no one would answer the door when he knocked. He was a large white male (maybe 6'2", 220#) with long hair, past his shoulders and his whole face was tattooed to look like a tiger. Can't understand why no one would answer their door.
