While me and my mother were browsing the vitamin aisle at the Eagan Costco, we were aggressively approached by one of the sample lady's who was stationed at the vitamin location. We were not looking for advice but she did not seem to care. She aggressively spoke at us for probably 5 minutes about these vitamins she was selling that neither of us were interested in. Then she pressured my mom into taking some supplements that later made her feel very ill. I was not pleased with the forcefulness of the sales associate and it was very uncalled for.
