An unhappy McDonald's customer has claimed he was handed an "unacceptable" burger bun, which the chain's manager later admitted had "gone off".
Mayron Romagnoli visited the Bedminster drive thru branch when he got the burger in question.
He said the condition of the food was "absolutely unacceptable" - but a spokesperson for McDonald's said the "toasting process caused a discolouration".
Mayron told Bristol Live: "Went to McDonald's today and got served this... Just thought it was absolutely unacceptable for a restaurant to serve something like this and for it to go unnoticed.
"I went through the drive thru and when I noticed, I returned to the restaurant and was offered a new batch and a refund. However it just seemed like they replaced the food and could have gotten a new bread from the same batch... in other words, how would I know?
"Just thinking if it was a child, they wouldn't know any different other than to eat it...
"Don't understand how it managed to get to me in the first place, considering how many chefs it must have gone through in the first place."
Mr Romagnoli was rather surprised by the manager's response to the entire situation.
He says when the branch manager inspected Mr Romagnoli's burger, he admitted: "Yeah, this is gone off."
Mr Romagnoli said: "I was then offered a new meal. I then also had to awkwardly ask for my money back which he accommodated."
McDonald's response
A spokesperson for McDonald's said: "Food safety is of the utmost importance to us and we place great emphasis on quality control, following rigorous standards to avoid imperfections.
"While we are disappointed to hear this customer's experience was not a positive one, we would like to reassure them this was not a mouldy bun.
"In this case, a fault in the toasting process caused a discolouration, which should have been spotted at the time.
"As soon as the restaurant team were made aware, the customer was offered an apology and a replacement meal which they accepted.
"If the customer would like to discuss the matter further we would encourage them to contact our customer service team."
