Washington State, I Went To A Store And Was Handed $40 Bucks I Thought I Dropped, It Wasn’t Mine And Now The Store Is Threatening Calling The Police

Went to the potshop with $140 dollars. Got IDed at the door, stood in line for a couple minutes and security comes up and says you dropped this and hands me $40 bucks.

I was super relieved because I thought i actually lost that money. Spent $100 dollars (it wasn’t all for me) and even tipped.

Later, I’m counting the money in my wallet and realize I truly am up $40 bucks.

The pot shop has called me three different times and is now threatening to get the authorities involved. I don’t understand how any of this is my fault I even have messages from my stepdad asking did you give me an extra $40 cause I was so confused.

It wasn’t malicious I literally was handed the money.

EDIT: Guess I’m gonna return the money at my convenience. I was 80 miles away before I realized the mistake. I won’t be patronizing that store ever again and I’m going to ask for an apology for threatening legal action before they actually got me on the phone. Left me a voicemail saying they’re going to the authorities.

I am completely at a loss how I got turned into the bad guy when I literally thought it was my original money and how I should have checked everyone of my pockets before I accepted something someone said was mine.

I commend every one of you saints who have never found a dollar on the ground and pocketed it. Please don’t fall when you look down off that high horse
