bad service

pick n pay cashier Dont know the meaning of customer service ,they think they are doing us a favour by working at the till they have attitude forgetting that with out us client they won't get paid and also without pick n pay client won't eat so we need each other .I think pick n pay should have a box in front of the tell they client can use it for any suggestion or bad service or good service .During the festive season the shop is packed to the extend where one do shopping after standing in a long Que client decide to leave they trolley full of groceries.I bought 5 item ..the big tills where so full ..the express till where so full.Because of the so sign at the kios I went there with my 5 small item to pay since they were only 3 people I was the third one ..I put my small items on the counter Lindiwe with bad attidute told me to go start I Que cos she only assist people with 3 items ..stranger e nought there were no sign tgat only 3items can be paid there funny enough last week I paid my groceries in that same till why I was told to pay at the big tills ..if they told me I was not going to pay there again .Clearly pick n pay staff they need training to treat customer fairly
