Marshalls review: Customer service

I was shopping today, and come across a yellow stickers sale, most items were super cheap. When at the register, cashier named Alex, a young man, also his name tag said "coordinator" below the name was inspecting every item, peeling stickers, especially pair of pants, which were marked down to the $1, he said that it looks like sticker doesn't belong there, put the pants aside, called the lady, and asked her to see if the price was correct. She did that, and said yes, it's a $1. This made me feel very uncomfortable, I guess the point Alex was trying to make is that I put the stickers on? I most definitely did no such thing, and never had a problem at this store. I only purchased a few items, my total was $11.98. Why was I treated this way I don't know. Thank you for listening.
