Some people have lives (or wives). Some folks are just plain tired after 1 game. Could be a million reasons. Personally I like a little time to either bask in victory or sulk about defeat. Then of course there are the social drinkers who time their alcohol intake to just be able to finish 1 game. Favorite television show, the dog is whining by the front door, the kids want you to check their math homework, the cat just threw up (again), or maybe, just maybe, your deepest suspicions really are true and people don't like you....
What does mean, when a player refuse to rematch ?
Sort:
It doesn't mean anything. People simply don't feel like playing you again. There may be a variety of reasons.
There's two point of views to consider here:
1) The person does not rematch after he/she lost
2) The person does not rematch after he/she won
From a practical standpoint, it makes little sense to rematch someone who you beat, unless you are sure that you can beat them again. The reason being is that you have just taken away their points, so beating them again will give less points back each time. Also, the person will adapt your playing style and/or lines and you are essentially giving them a second shot to beat you.
If someone loses and does not want to rematch, it is probably because that person is not confident that he or she can beat you.
That's my opinion on the issue.
Ty for these answers.
But no answers speak about analogy with Milgram's experience.
I just can't tell you that subjects of Milgram's experience have the same kind of justifications. It's become very interresting. I would like other answers.

(sorry for my bad english, i'm french).
oui oui moiseur They seek him here they seek him there those frenchies seek him everywhere is he in heaven or is he in hell that darned elusive Pimpernail
I'm so bad at blitz that usually I lose a bunch of games before I win one. Since I always want to end with a win, I'll stop playing after I've made it, or I'll find myself on one of my legendary losing streaks again and sit there for another couple of hours.
I would think a rematch is usually made by the party that lost! 
Sooo should I play you right away or do I feel I was lucky and another game you may just kick my @zz?? The winner is always in the driver's sit and can say later baby. Thats a little rock & roll era stuff. 
Upon further consideration i must indububly respond to ones mental condition for failing to respond to said challenge.Its obvios they are suffering from symtomatic manias which having been imposed on their psychy has deranged their libido to paranoic states of traumatic repressions compounded by inferiorities and deep rooted fixations which give lien to psychoneurotic manias causing catostrophicly diversified tendencies! QED
Is this really a topic worth discussing?
Is someone trying to piss me off by saying gg
I don't like rematches because rematches make me lose.
I do it all the time. It means I don't want to play you anymore, simple as that.
Its not that I'm afraid to lose rating points or something as silly as that. Its usually because you played a silly opening/plan and whether I lost or won, I'll still have a bad taste in my mouth. Or rather, I just don't see the point between playing you or some other random player. At least in the latter case you could say there's some variety.
I truthfully on principle refuse rematchs unless you've impressed me on the board on in chat.
Cool
If you play in a club match usually you play two games. There isn't any question if they will play another game. An opponent who didn't want to play me again just didn't start the next game and lose for failure to move.
They were rated games, but the second one didn't count.
I always say "Thanks for the Game" if they lost or good game if it was a good game. My ant talks for me.
I rarely play three games in a row, when I play one game, I feel bored, excited, and like to walk around at home.
Some members are tired enough to play another game that's why they refuse to a rematch. Some have lives or have to do work.
And I also am refusing to a rematch if I feel that my connection is bad.
Although a player should rematch in the true spirit of the game -A player still has that option of remaining in play
I always refuse rematches, I don't want to play someone I juts lost or won from, maybe If I draw.
I just want to get your point of view about this situation.
What does mean, when a player refuses to rematch on rated game ?
I ask this question because 97% of players on chess.com refuse to rematch.
Before to answer you will find the same percentage on Milgram's experience.
So what does at mean ?
