A cancer survivor who lost his nose and left eye to the disease is heartbroken after being asked to cover up or leave a restaurant because he was supposedly putting off customers.

On Wednesday (NZ time), Kirby Evan's daughter Brandy posted on Facebook about her father's experience at Forks Pit Stop in South Carolina.

According to Ms Evans, her father had visited the gas station for something quick to eat, but, after sitting down, was asked by the owner to cover his face if he wanted to eat there.

In tears, Mr Evans left the diner and went home.

Now his daughter has gone public with the story and warned the public, and the owner, that "cancer does not discriminate".

"My father is the strongest man I know but, as he told me what happened to him, I watched tears roll out of his eye," she wrote.

Ms Evans went on to say that her father had been on a fixed income and couldn't afford to pay for surgeries, and wearing an eye patch irritates the raw eye socket.

The post has gone viral on Facebook, receiving over 7000 likes and 11,000 shares.

A GoFundMe account has been set up for the cancer survivor, and has so far raised nearly US$69,000 (NZ$106,000). It will reportedly be spent on paying for surgery and care for Mr Evans.
