Poor customer service

Cosmo Mall Pick n Pay. Poor customer service by Caroline Lekote (teller) and Sithabile (didn't get his Surname. He is a manager) they both failed to adhere or to put measures in place and ensure the 5 or less queue is strictly for 5 or less items. When I raised this, I was told "tell the customers not to come with 5 or more items in this queue" That's not my job it's their responsibility and they failed. Pick n pay shouldn't put signage if they themselves are not going to follow it.
