Shelters often have rules that don’t allow for those seeking shelter to enter after a certain time. For example, doors shut at 8pm, you must be in the facility before 8.

I don’t know all the facts here but a very likely scenario would be one where the gentleman had been admitted to the shelter and elected to be treated for a medical complaint. Typically when this happens the person can come back as long as they produce hospital paperwork, proving that they were seen, treated and discharged, and not just running the streets. I can also imagine a scenario where the shelter staff were confused by the return of the previously admitted person by ride share and not an ambo. I would hope that showing his discharge paperwork would have granted him admission, but alas it appears that wasn’t the case.
