Ring problem, very very very confused

A woman went into a jewelry store, chose a ring worth a thousand dollars,
paid and left. Respareceu in store the next day and asked if I could
exchange it for another. This time chose one that was worth two thousand
dollars, thanked the jeweler kindly and prepared to leave. The jeweler,
of course, required more thousand dollars. Outraged, the girl said she had
already paid him the day before the value of thousand dollars and he'd
just give her a ring worth thousand dollars. So nothing
owed​​. He left the store, leaving the jeweler disoriented.
Confuse?! rsrsrsrsrsrs
