Idioms are very common in the book. The time period's lingo and style was full of them, like "canned" (to get fired) and "in hot water" (in trouble). The most commonly used idiom in the book is used by Lennie. "'An' live off the fatta the lan',' Lennie shouted." (Stienbeck 14) Lennie really likes to say that when he and george are daydreaming about getting the house. Steinbeck's writing style has been noticed by critics: "Mr. Steinbeck, as I have already suggested, writes with great technical adroitness" (Krutch 340). I agree with the critic. Steinbeck really get into the speech and lingo of his characters. It takes skill to use so many idioms. I think he uses idioms very well.
