On a main drag here, with concentration of nightlife, and also a concentration of street people, one upscale fast-food place started going cash-free at night. I don't know whether that was because they were concerned about robberies, or because they didn't want any of the street people sitting in there and making it less attractive. (Like in another nearby fast-food place.) Cash-free can be a conscious way to avoid serving much of a socioeconomic demographic you don't want to serve. A bit like the past practice of refusing to serve certain racial/ethnic groups, and posting signs stating that.
