A mum has vowed never to visit a branch of McDonald's again after staff refused to let her two-year-old daughter use the toilet.

Bernie Henderson, 36, was turned away from the Grimsby branch on Saturday (August 4) because she was not a paying customer.

Her daughter, Vaida Mae-Dale, 2, can't control when she needs to use the toilet as she is currently being potty trained.

The 36-year-old said she was "fuming" and "livid" at McDonald's refusal and thinks it's wrong to turn away children who need to use the toilet, Grimsby Live reports.

Bernie said: "It was just awful.

"I've been potty training Vaida for a while now, but I can't control where and when she needs the toilet.

"We'd used toilets in town before, we entered the vape shop on Victoria Street. Having explained that I would need to get my daughter to the toilet, they suggested I go across the road and use the one in McDonald's.

"Taking their advice, we walked across the street into McDonald's. Only two steps in I was stopped by someone who worked there and asked if we needed any help.

"I asked if I could borrow the toilet for my daughter and she just kept telling me that it was only for customers to use.

"In the end I had to take my two-year-old daughter all the way across town, just to go to the toilet.

"I can understand why you might turn some older people away because you don't want them causing issues, but not a young child."

Following the incident on Saturday, the branch manager has contacted Bernie to apologise.

A McDonald's spokesman said: “We are sorry to hear about this lady’s experience.

"As soon as they were made aware of the situation, the restaurant manager apologised and the restaurant crew were reminded of our expectations on how they should deal with similar requests in the future.”
