How mortifying would it be? To propose to a woman in public and to see your proposal rejected outright.
That seems to have happened to the gentleman in the below vid. He stopped his girlfriend at a mall, took out his ring, got to one knee and proposed.
In the presence of a gathered crowd, she said no!
After the guy’s heart was broken, the crowd kept filming what was happening, with some even bursting into laughter.
Watch…

…Luckily it was a social experiment to see how people would react to such a situation. Turned out most of us would laugh at such misfortune.
