No service from staff

Yesterday I went to Makro Centurion to purchase a new printer and USB. I walk in go straight to the printer put it in my trolley and as I am about to walk away a staff member approaches me asking if they can just put their sticker (commission sticker) on the box, I said no and walked on to the USB case. I waited for 10 minutes with no service. I went to a floor manager asking for someone to open the case for me. She calls a staff member that is just floating around the laptops, and that was the same staff member whose attention I tried to get twice before going to the floor manager. After he opened the case I took what I needed and he also just wanted to add a commission sticker. This issue of staff not giving any service, but just waiting for people to purchase stuff so that they can place their stickers is unacceptable. Aren't they suppose to deliver a value added service to the customer instead of just running around wanting to place their stickers. The only people that approach you are the people trying to get you to buy something that you do not need and try to stick all kinds of flyers in your hand.
