Would you tell someone...

Yes it's embarrassing. But try to think of it, it's more embarassing if many will notice it right, so as soon as you notice that to someone I would rather tell him/her immediately but in a good manner. You can tell that person privately.That depends actually on how you react from it, person as we are make mistakes. So it's ok if you were told immediately than you were told late and you face a lot of people already, it's more embarrassing.:)

I think if i knew them i would drop a hint and then if they did not take the hint then i would have to tell them as i would want someone to tell me if i was the same.
