I am writing a pivotal scene for my novel that is set in Red Square of Moscow. A very wealthy bureaucrat is leaving a famous, high end store that exists in real life.

Is it considered copyright infringement to mention the names of actual businesses or services (like hailed an Uber cab) without obtaining expressed written permission from the company? One legal site gives several examples stating that as long as it doesn't cause the corporation harm it's okay, but that sure seems open to interpretation if one were writing a story suggesting a murderous Santa is lurking in Macy's.
