I was turned away at a Disneyland bar — the reason why is frustrating and could affect other visitors

The force was not with this ill-prepared excursionist.

An avid Disney fan was left baffled after being barred from buying an adult beverage at a popular theme park drinkery — apparently running afoul of a little-known US law.

The Canadian traveler arrived at Oga’s Cantina inside Galaxy’s Edge, the Star Wars-themed section of Disneyland in Anaheim, Calif., with his provincial ID and a digital copy of his passport — only to find himself stymied by staff.

Only an original passport would be accepted as proof of age. they told him.

The thirsty 26-year-old later took to Reddit to bemoan the bar banishing — where he quickly found out that the policy is, in fact, a well-known California law, which Disneyland is naturally subject to.

“The bar must be as important as an airport with the level of scrutiny they give you,” the cross Canadian complained.

Despite the fan’s frustration, he found himself faced with “no sympathy,” as one commenter succinctly put it.

“In fairness to Disney, they specifically have a section in the FAQ addressing this,” wrote a park rule buff.

Meanwhile, another said: “Why would they accept a scan? So easily altered.”

“I guess the silver lining is that I don’t have to pay for the overpriced drinks, but it’s just a little frustrating,” the Redditor said.

The Star Wars-themed snub comes amid a decline in tourism from north of the border — which Disneyland in particular is hoping to combat with extra enticements for timid Canadian travelers.

Though many Disneyland rules and regulations are fairly straightforward to the average sightseer, the House of Mouse has some sneakier statutes — especially where the strict dress code is concerned — that can trip up ill-prepared guests.

Refusing to follow the dress code can even get you booted from the happiest place on Earth.

Costumes worn by adults, inappropriate or scary attire, and offensive tattoos are often grounds for a scolding from park officials at the very least, but refusal to change or cover up the offending outfit is one way to get a Fast Pass out of the park.

Disneyland recently celebrated its 70th anniversary with a brand-new exhibit that included an animatronic of Walt Disney — which some disapproving die-hards have called “shameful” and “embarrassing.”

“I think I started crying,” a granddaughter of the entertainment industry legend complained. “It didn’t look like him, to me.”
