['I found a phone, cards and money in the washroom at the mall. I gave it back in customer services', 'THat is extremely noble of you!   YOu did the right thing!!', 'Yes because if this happens to me I would like to get my things back too.']
I would too.  I have lost things before and never had anyone turn them in and its not a good feeling.
I found someone phone with cards and money at the mall. Because it was not mine, I returned it and gave it to customer services.
