I lost my iPod and i don't have iCloud or Find My iPhone installed?

Okay so me and my mom and friend went out today, we went to the nail salon (brought my iPod back) and then we picked up my little sister and dad to go out and eat at a fast food restaurant, (THOUGHT i bring my iPod back) then we went to go my friends house to take her back home, i thought i left my iPod in the car but i didn't. I left it at the fast food place. It was outside where we was sitting, so it could've been anybody who took it, but i think it was the worker there, because he was laughing at us, But anyways. I don't have iCloud or find my iPhone installed, and i don't want a new one. I don't have dropbox, either. Pictures, videos and information is all i really cared about - I have a passcode lock, but i don't know if that helps

If you have some form of a 3rd party app installed on it that has calling-texting features on it you may text-call in an attempt that someone will answer. (Assuming the iPod is connected to the internet). Besides that you would need some form of hardware already on the device to physically track it. Besides that, just go back and ask around.
Best of luck. :/

Dang that sucks. I'm sorry to hear that. Just go back and look round for it.

If you didn't turn on find my iphone then thats just being lazy, consider it gone and move on.
