Broadway Avenue Rite Aid Pharmacy in Seattle uses their marquee as intended
In DC, CVS has bought and converted many former theaters into pharmacies. While they've kept the marquees to many of the buildings, they have de-theaterized the marquee for all intents and purposes. They certainly don't use the marquees to communicate "current" and "coming" attractions like flu shots.
The CVS in the Brookland neighborhood of DC is located in the old Newton Theater.
Newton Theater back in the day. Note that movies were listed in an information display under the marquee.
That's not the case, fortunately, with this Rite Aid Pharmacy on Broadway Avenue in Seattle.
