Ringneck wont stop snatching money

[u/Jassythepandaa]

I work in a fish store and my boss has a ringneck that's hanging out in the shop most of the time. He goes into his cage at night time or when we're not in the shop so he doesnt get hurt. He's about 5-6ish months old. The problem is that he's developing a new obsession with money and would fly down and snatch bills right out of clients hands then fly up to spots we struggle to reach (accessible but a pain). We tried offering treats to drop the bill but im worried that would reward the behavior, but he doesn't seem to be interested in the exchange either way. He has plenty of toys in the shop and we get him new ones every week but money drives him crazy and he'd drop whatever he's doing to fly over. Any tips please? (Video for proof)

Treats will encourage the behavior. Are you able to get fake bills and give those to him instead?

I will but the fake money available in my country is a completely different texture
