I went to Walmart yesterday to buy some cleaning supplies. One of the items I purchased was a 2.50 scrub brush. When I took it to the register it didn't have a tag on it, so I went back to get one for her to scan. I went through my bags tonight and noticed the cashier had given me both by accident and only charged me for one. I have other items to return, and have the receipt for them. But I'm wondering if they would be able to tell who the cashier is by the receipt when I return the other items? I was taking the extra brush back with me and tell them what happened, but I don't want to get her in trouble over 2.50.
