The New Yorker has a great story by a reporter who pretended that various animals were her emotional support animals. She showed up with a turtle, a pig, and an alpaca at various institutions - always with a letter saying the animal was an emotional support animal (E.S.A.).
She and her borrowed turtle got into the Frick Museum.
She and a small pig got on a Jet Blue flight.
The pic at the link shows here with an alpaca in a drug store.
Why didn’t anybody do the sensible thing, and tell me and my turtle to get lost? The Americans with Disabilities Act allows you to ask someone with a service animal only two questions: Is the animal required because of a disability? What work or task has the animal been trained to perform? Specific questions about a person’s disability are off limits, and, as I mentioned, people are baffled by the distinction between service animals and emotional-support animals.
Take your pig on a plane,
take your turtle among the Vermeers,
just claim it's an E.S.A.,
and you're in the clear, it appears.
