While the games were viewed as a success for Klein and the city of Calgary, it was not without its issues. Residents had been promised that only 10 percent of tickets would go to "Olympic insiders", IOC officials and sponsors, but OCO'88 was later forced to admit that up to 50 percent of seats to top events had gone to insiders. The organizing committee, which was subsequently chastised by mayor Klein for running a "closed shop", admitted that it had failed to properly communicate the obligations it had to supply IOC officials and sponsors with priority tickets. These events were preceded by OCO'88's ticketing manager being charged with theft and fraud after he sent modified ticket request forms to Americans that asked them to pay in United States funds rather than Canadian and to return them to his company's post office box rather than that of the organizing committee.
