Diana Carrillo was asked to prove she was in the country legally to be served alcohol when her friends went to Saint Marc Pub-Cafe

A group of friends in Huntington Beach was stunned when a waiter asked them to show proof of residency before he would serve them drinks.

Diana Carrillo, 24, shared the offensive experience on Facebook and the restaurant has been bombarded with negative reviews ever since. The waiter, whose name was not revealed, was fired.

Carrillo, her sister and two female friends went to Saint Marc Pub-Cafe on March 11 and were told by the waiter they needed to prove they were 'from here'.

Carrillo was especially taken aback because her parents are immigrants.

The friends were baffled by the apparent racism and were not sure if the employee was joking at first.

Kent Berden, the senior director of operations at the restaurant told the Orange County Register the waiter claimed he was joking but Carrillo is not convinced.

As an apology, Saint Marc's offered 10 percent of the weekend's profits go to a charity of the women's choice. They also invited them to be VIP guests but they declined.

Carrillo chose the Orange County Immigrant Youth United as the recipient of the restaurant's donations.

She told the Register she is worried incidents like these will continue because of the political climate surrounding immigration.

She said: 'I feel that’s the direction we’re headed in, given who’s the president.'

'That’s one of the reasons I posted it on social media rather than just dealing with the restaurant.'

The viral post on Facebook by Diana Carrillo read: 'A few friends and I went to Saint Marc's in Huntington Beach today. My sister and my friend were seated first and the waiter asked them for their "proof of residency" when they ordered a drink.'

'My friend in disbelief repeated what he said and his response was "yeah, I need to make sure you're from here before I serve you." Not knowing that this happened to them, my friend and I were then seated and he returned to the table and asked us for our "proof of residency." After fully digesting what he said, we all got up and left to speak to the manager. '

Carrillo's post was shared over 600 times on Facebook about the waiter's racist comments

'For a few seconds I thought maybe he was being a smart a** or joking but the fact that he said "I need to make sure you're from here before I serve you" was completely unacceptable. How many others has he said this too? I hope this employee is reprimanded for his actions. No establishment should tolerate discriminatory actions from their employees.'

Her sister Brenda Carrillo wrote on Facebook: 'Regardless of race or ethnicity, I don't believe anyone should ever be treated the way we were on Saturday. I really feel for the people who this has occurred to and were too afraid to speak out due to immigration status etc. If we don't speak out now, people will continue to believe that they are entitled to treat us, minorities, as less.'

'We all deserve a seat at the table.'

Since the incident the restaurant has been blasted with negative reviews on Facebook.

One wrote: 'Racism is a menu item I can't stomach.'

Another posted: 'I cannot support a establishment that blatantly discriminates against a large portion of our population.'
