Monday, 19-year-old David Halliday was working at his job at a spa concierge at Pechanga Resort and Casino when Shah came in as a customer.
Halliday described Shah as difficult, demaning service ahead of other guests.
"He came in with his girlfriend," Halliday said. "Just from the offset, he seemed a bit different from the usual guests we have in the spa."
Halliday also found it unusual that Shah was paying with cash. Feeling like he might have seen Shah somewhere before, Halliday googled his name.
When numerous stories about the ticket scam came up, Halliday remembered seeing coverage on local news. He called Pechanga security, who brought in the Riverside County Sheriff's Department. Deputies arrested Shah without incident.
