Decline the draw then get mated

Have you ever declined a draw then been mated? I have. Have you been on the other side - offer a draw and then mate the guy after he declines? Pretty shameful/great experience, depending on which side you're on.

Yeah, I've had a few. Opponent won't draw and tries to avoid repetition only to lose later.

It is very common. There is nothing shameful or great about it. The result of the game doesn't change the validity of the offer or the rejection.

Makes you feel like an idiot.

If it makes you feel like an idiot then you are one.

Can't argue with that.

No, it's usually the other way around

I've declined offers of draws before where I felt they were reasonable and that there was a risk of being mated if I continued - generally only if I thought that the position was interesting enough that it was worth risking a loss for.

When I lose that way it doesn't bother me.

I must admit that it is a great feeling when you beat someone you offered a draw to...

I prefer to accept a draw whatever the position on the board 

Horrible!

(Note to myself: Offer draw in a losing position while playing Mottley.)

some fear losing so they never resign, I fear winning so I offer draws...

LOL!

Been a while since a comment has made me smile on Chess.com, good one Muhammad.
