Do you use cheats?

If it's a singleplayer game- I can use cheats, who cares?I use 'em if I completed the game and going for replaying it to check every corner of it after.
Sometimes I use cheats when I got bored of gameplay and don't care for it anymore, but I'm interested in the game's story and want to see it to the end.

But when it comes toCS orother multiplayer games - using cheats while playing with people -it's likebeing a pig. I have more respect for myself than that.
