Math

Our cafeteria doesn't take money. The front desk sells sheets of meal tickets for 10 kuai. They are printed on a material less substantial than tissue paper and come in three colors: white, pink, and yellow. White is 2 kuai, pink is 1 kuai, yellow is .50 kuai. Today I ate two eggs and two dumplings for breakfast. Normally that's 4 kuai, but the regular woman wasn't working and her replacement charged me 2.50 kuai. Score! I gave her my sheet of five white tickets. She gave me three whites, six pinks and a yellow in return: 12.50 kuai. Hmm... that makes today the first time I was paid to eat. And hopefully not the last.
