I have been into this store the third time this week to buy bedding. Went in today to pick up some more, the lady on the cash desk was busy so i went down stairs to get some shoes. So i was going to pay for the bedding down there. I noticed an older man following me, has i was looking at the shoes i noticed the man telling two lady assistants watching me. I brought shoes, childrens clothes and shoes for myself, which i paid for all together. Made me feel very uncomfortable. I buy a lot out of this store not keen on going back now.
