Man asks his girlfriend to marry him by hiding the ring in a fast food chicken sandwich

A Facebook photo shows a picture of a diamond ring sticking out of the bun of what appears to be a Wendy's chicken sandwich. 

A happy bride-to-be posted a photograph of her new fiance's marriage proposal on Facebook. 

Her only comment: 'I said yes.'

Anna - whose last name is obscured in the photo - appears to have been won over by the chicken sandwich.
