Pensioner Daphne Kingdon, from Spinney Hill, thought she would not be allowed into the town centre art gallery until the Prince opened the door for her and asked her to come in.
She said: "He shook my hand outside and asked me if I was coming in. I didn't think I'd be able to get in, but he took me with him. It was quite exciting.
"I met Diana once and shook her hand too, so it was really nice to meet the Prince."
The Prince visited the town centre art gallery to meet youngsters who have set up their own businesses after taking part in schemes organised by the Prince's Trust.
But before he could meet the business leaders, the Prince was interrupted by six-year-old Reami Fleming.
