Maya Makri was asked to leave a Tesco Express in North London this week because of her guide dog.
Staff told the 39-year-old that no pets were allowed in the store, and refused to accept otherwise even though the her dog Jemma, pictured below, was clearly wearing a high-visability harness.
Speaking to the Evening Standard Maya said "Various customers tried to back me up, but we were shouted down. I burst into tears outside the store in sheer frustration."
Tesco have now apologised to Maya and donated £5000 to a guide dog charity.
Maya, who is a student at the Central School of Speech and Drama, said that this is just one incident out of many she has encountered since moving to London 10 years a go.
Maya has said that she has been asked to leave many restaurants and has struggled to find a local gym because of her guide dog.
