This happened years ago I purchased some hair grease from a seven eleven convenient store. I decided I didn’t want it, so I took it back to the store the same day. When I got there, I went to their office to speak to the manager and had to wait for him to come out and when he did, he asked for the jar of hair grease I didn’t think nothing of it at the time I just handed to him he said he’d be right back. He went towards the back of the store. When he came back to the front, he said that couldn’t take it back, so I asked him why? That was when he opened up the jar, I looked down in it someone had stuck their fingers in it. I had no clue never opened the jar I had way of knowing. Talk about regret I regret ever going to that store. To be honest I think the manager put his fingers in there because he didn’t want to give me a refund.
