Bad to none service from staff

Today at the Carletonville Pnp we stood in the express lane for almost 20 minutes due to people coming to the express lane which had alot more than 10 items. We looked for the floor supervisor and told him to explain to us the policy of the express lane as we arr standing here and the tellers are allowing everyone with more items than the notice they have at rhe express rill. He went to the tellers and didnt even stop or asked them why they were allowing. The tills for items which are more tha 10 was extremely long however they were faster tha the express lanes. When I questioned the floor supervisor on why he did nothing to our complaint, his response was, he had to first ask the clients why they stood they in the wrong que. I told him the service was pathetic to say the least. He just had such a don't care attitude.
