"It's not right. It's not right," said Murrieta resident Allison Brown, choking back tears.

For Brown, the emotions are still raw, two weeks after a lunch stop at a Vista Subway restaurant on 1906 Hacienda Drive.

Brown said a young worker greeted her and took her order for a 6-inch tuna sub sandwich and two flatbread "Flatizzas" -- one for her and the other for her husband.

When she got home, she couldn't believe what she saw.

"When I took it out, I saw 'Big Mama' … What is this?" said Brown, who added she has always been conscious of her weight.

The words "Big Mama" were written on one of the Flatizza boxes.

"I was hurt. I was devastated. I was crying," said Brown.

Brown was a loyal Subway customer, and she told 10News she was inspired to eat right by Subway spokesperson Jared Fogle, known for his weight loss off the Subway menu.

She said that's why it's so unbelievable the message was written by a Subway employee.

"It's not nice to be picked on. It's not nice to be made fun of. This really destroyed me," said Brown.

When Brown went to the franchise owner of the Subway, she said he apologized and told her this about the worker: "He just said he doesn't know better. He kept trying to explain it to him and his worker didn't get it," said Brown.

Frustrated, Brown hired attorney Dan Gilleon.

A letter was sent to Subway's corporate office that stated legal action was possible. However, instead of money, Brown wants anti-discrimination training led by an outside firm for all Subway employees.

"This was discrimination, harassment, teasing, mocking somebody -- a customer," said Gilleon.

Brown said she's coming forward to speak out for anyone who's been ridiculed for their weight and never spoke up.

"We all come in different shapes and sizes, and then you see something like this … 'Big Mama'? How is that helping anybody?" said Brown.

In statement, restaurant owner Sanjiv Mehta said:

"As a small business owner, I do not tolerate discrimination of any kind. When I learned of this incident I immediately investigated and disciplined the employee involved. I also made contact with the customer in an effort to resolve this matter."

 Subway has yet to respond to the incident.

"They were contacted soon after the incident and they've basically blown my client off," said Gilleon.

"I will never stop foot in a Subway again. You couldn't pay me to eat there again," said Brown.
