As happens late at night or in the early morning hours, "interracial" couples (of some combinations) returning to hotels get this kind of "prostitution-alert" treatment at hotels -- from the front desk or "security" staff -- way more often than couples formed by those who appear to be of the same ethnic/"racial" background as each other. Hilton isn't unique in this regard, as the same kind of dynamic plays out at hotels of other brands too. It's sort of an industry problem juxtaposed with a "see something say something" kind of paranoia that leads to various sorts of ridiculous outcomes such as this one involving stimpy.
