INDIANAPOLIS A woman who worked catering events for the University of Notre Dame says it was her lucky day when the school tipped her $29,000 in her check. But now the university is suing to get back the money she says she's already spent. Sara Gaspar of Granger says in court documents filed this week that she "thought finally something wonderful had happened" in her life when the school paid her a $29,387 tip on April 17. She said in court documents that she called the school's catering department three times about the payment, but didn't hear back until she received a threatening call from the school in June. Gaspar says by that point, she had spent the money on a new car and bills. Notre Dame contends Gaspar should have been paid only $29.87, but was overpaid because of a typing error. The school says in a lawsuit filed Aug. 27 in St. Joseph Circuit Court in South Bend that Gaspar did not notify the school about the error, and instead spent the money knowing it wasn't hers. Notre Dame says it discovered the mistake in May and requested repayment, but Gaspar refused. The lawsuit accuses her of unjust enrichment, fraud and conversion.
