I keep getting framed

So I do a mini job, 3h once a week. 

And it's just putting stuff into shelves at a store. 

But each time, the supervisor notices something, that either doesn't belong into that location or it's placed the wrong way or like overfilled. 

And let me tell you

IT WAS NOT ME. IT WAS THE PERSON WHO DID IT THE OTHER DAY. I'VE NEVER EVEN TOUCHED THAT SPECIFIC PRODUCT. 

Like bro why ya gotta do this to me. 

And like they tell me if I see it, I should just fix it. But I haven't even seen it yet, cause I didn't put it in and was focused on the stuff I have to put in. Like dude, come on, I'm focused on finding the right spot for the bottle in my hand, how am I going to notice that a product I never had to place is out of place? 

I swear, there is someone framing me, making me look like I do a shit job with their mistakes. 

Like how do those mistakes not get noticed till I'm there for my 3 hours lmao
