Five Below, the discount store on Irving in DCUSA, posted a sign in their window saying that "student" (sic) were banned from coming into the store from 9am-3pm, and that only 5 "student" (sic, again) could be in the store at one time from 3-7 pm.
Presumably kids were goofing around in the store, but it seems odd they can ban a group of people. They also had some typo problems on the sign, it should be "students" and there were some stray semicolons in there.
One would assume that kids should be in school from 9-3, though maybe some have early dismissal.
Twitter user Michael Hechter clued me into this weirdness.
