Oh Jews, Jews...

The Israeli Crossword Puzzle Championship is taking place in Tel Aviv. Among the serving staff is Mari, a girl of Estonian origin, who thinks: “If I serve the solvers well, they will each give me a $10 tip. But if I try hard, they won’t mind $25!” Mari hovers around the crossword solvers throughout the competition. She offers them water, coffee, and various snacks, exchanges solution sheets, etc. She runs out of leather. And when the competition ends, she waits with hope. The crossword enthusiasts start to leave. The first one says: “I have participated in many competitions in my life, but no one has ever served me as well as you. Thank you very much!” He shakes Mari’s hand and leaves. The next ones do the same, but no one gives a tip. The last one, a small old man, says the same thing and adds: “My competitors and I decided to thank you. Here is a check for $10,000.” Mari stands at the door, wiping the cold sweat from her forehead with one hand, waving at the competitors with the other, and whispers: "Oh Jews, Jews... Maybe you didn't kill Christ, but how you tortured him!"
