<human>: My friends and live in a small town and apparently the man who proposed knows the owner of the theatre we went to last night. The man who proposed got the guy who owns the theatre to show a mini power point of the good times he and his fiance of 4 years spent together. The whole time the woman was red faced and tearing up, and at the end of the powerpoint, there was a slide that said "will you marry me".He then proceeded to get on one knee and attempted to give her a diamond ring. To the astonishment of the whole theatre, she said no, kicked the diamond ring out of his hand, called him a good-for-nothing liar and ran out of theatre. It was the most embarrassing thing i had ever witnessed in my small town (that's not saying much).

Can you condense the text into a few key points?
<bot>: Guy gets turned down  rather awkwardly in a theater after orchestrating a beautiful proposal. So reddit, whats the most embarrassing scene you have ever witnessed?
