More so than in many team sports, good sportsmanship is an integral part of curling. For example, celebrating an error by the opposing team, fully acceptable in some sports, is frowned upon in curling. Even at the highest levels of play, a player is expected to “call their own fouls,” so to speak, such as alerting the opposing skip if they burned a stone. It is also traditional for the winning team to buy the losing team a drink after the game. (This is in interesting contrast to the game of darts, where the loser traditionally buys the winner a drink by way of congratulations.) This is often referred to as the Spirit of Curling. It is not uncommon for a team to concede a curling match after it believes it no longer has a reasonable chance of winning but before all ends are completed. Concession is an honorable act and does not carry the stigma associated with quitting. To concede a match, the losing team removes their curling gloves (if they wear them) and offer congratulatory handshakes to the winning team. Thanks and wishes of future good luck are usually exchanged between the teams.
