Lost grey hat

Hello,

My husband was with our baby in a taxi today 21.12.2017. at 2:20PM and was going from the Blanchardstown shopping centre to the Joe Duffy Mazda service in Finglas. He left a grey-pink hat in the car. He paid in cash and stopped the taxi on the street so I don't have more info about the car or the license plates. The car was a grey Skoda, and a woman was driving it.
The hat is grey, and has small white and pink hearts on it. Please contact me if you have any info.

Thank you,

Ivana
