Opponent leaving instantly after mate.

Hi! today I played a couple of games where my opponent left instantly after mate. So instantly it's impossible to react. How is this possible? Sorry if bad English.

They're just salty
Also, your ping might be lower than theirs

So, what do you want else? Btw, wins or losses?

Well if the game is finished and it is a random opponent, why would he stay? No one can react to mate, there is no allowed move! If you want several rematches, you will eventually find someone who wants the same or you can ask on the forum to find such opponents.

So what I mean is that they leave *instantly*, faster than you can click new opponent.
Also it shows different end screen, there is only a small area where you can "request a rematch. Has this happened to you too?

@Sarg0n games wheremy opponent left.

Your question doesnt make any sense. Why does the speed of how fast people leave a finisheď game matter to you?

I'm just curious why it happens sometimes and sometimes Not.

If they leave instantly your question „rematch?“ has been answered, hasn’t it?

Well, some people leave a game instantly, some after a while. That is just how humans behave.

Some want a rematch, some don't.
Some want to chat, some don't.
Just human behaviour.

I understand of course that some people leave after a game. What I mean is that after I checkmate them they are just gone and sometimes it tooks a secound and the ending screen is different. It might be difficult to explain without a picture. Anyways it's not a problem for me, I was just curious.
