The croissant seemed smaller that what I remember in years past. Everywhere is cutting back.
The potato cake was a bit greasy and not crispy enough for my liking.
The polite staff made it worth the visit. The food not so much.
All in all you get what you pay for I suppose. Decent. Not great.
Corporate sent a message for me up further my complaint.
No way.
Carlos is in charge of the color of people’s skin when they come in the door to spend money. Dav agrees with him.
Carlos wins.
This white woman spends her money down the street at Burger King, McDonalds, Del Taco and Taco Bell, Popeyes etc.
This Jack in the Box does not need my or my friends and family’s money. Nope.imho.
Carlos wins.

Well 5 days later and no response from Nancy or upper management. Absolutely true my post. Carlos refused to charge me the posted price because I am a white woman. No question I am right about the Racism in this store from Carlos and Dav and Ereidi.
And again no free fries on Friday said Ereidi. This Racism against whites and elder abuse needs to stop.
So now I spend my money at Burger King, McDonalds, Popeyes, In and out burger. All down the street.
This store does not need my money. I am guessing Carlos & Dav will get a raise for cleaning out the white people from spending their money in his store.
Wait: Sept. 10, 2025.
After some thought, I think it’s best that Carlos & Dav be in charge of the color of the skin of the customers. I do not need to go into this Jack in the Box. There is another one that I also go to a mile or 2 away. After talking to some of my WHITE/Caucasian friends, they too will not go in this store and bother the employees.
Carlos and Dav win. It’s what Nancy and upper management want also.
But beware people! It’s also about over charging for food that posts a different price which Carlos refuses to honor. Do not let Carlos over charge you. Do not let Carlos abuse you, no matter your skin color. Elder abuse is against the law. Not honoring posted prices is against the law and fraud.
Also down the street is McDonalds and Burger King. They do not discriminate.

What is happening in this store??!!
Last night Carlos refused to honor the price of a burger that is listed on the board.
He insisted there is no burger for $2.49. I pointed to it but he refused. After a few minutes he still insisted in charging me the extra money which is thievery.
He said, I’m going to charge you this no matter what and I will take the cheese off but you will pay for it.
That is not right I said. I want the burger for $2.49 without cheese in the first place.
He said NO.
I am charging you what I want . So I asked for the manager but Dav was on break.
I told Carlos well forget it this is overcharging from a posted price. I guess I have to leave. He said good.
I see Dav tell him and he rings up the burger for $2.49 but he refused to show Carlos on the screen, I have a pic. Dav absolutely refused to teach Carlos.
So…. after a few minutes I realize that this is elder abuse, which is against the law. Fraud by an employee and Racism.
Carlos wanted me to leave because I’m WHITE. There’s no other reason. It’s posted 2.49 but Carlos insisted on charging me $2.99.
If I wasn’t going to allow him to overcharge me he was happy I was leaving.
It’s crazy his abusive behavior to me. Why?
Why is Nancy the manager allowing such abuse? Dav too.
AND I tried to get free fries on Friday. THIS STORE REFUSES TO GIVE YOU FREE FRIES ON FRIDAY. Isn’t this fraud too?
Below I posted Eneidi refused to give me the free fries. Why?
What is happening in this store?

It’s a lie people. You do not get free fries on Friday says the Supervisor in charge Ereidi. She laughed. She thinks it’s funny you drive there for food AND free fries and no fries.
I think it’s fraud.
What a bunch of Baloney! I am giving 1 Star because there has been no Air Conditioning for A Week!! It’s so hot in there! It’s been in the 80’s in Monrovia Ca. Step up owner/management! This is abuse to your employees! And customers! I have not seen any repair trucks and I have been buying food every day for a week. Fix the Air Conditioning!!
