I haven't read all the posts but i think these tills should be boycotted, they are a threat to jobs, thus making larger profits for the supermarkets, soon there will be no more till assistants, and the customer will have to serve themselves, just like we now do at filling stations.
Yes gone are the days when the customer sat on a chair by the shop counter while the shop assistant moved along the stock shelves gathering all the shopper's list of goods.
And those days when no matter how bad the weather one could remain seated in one's vehicle while the petrol pump attendant filled one's petrol tank, and then checked the oil and radiator levels and finally wiped one's windscreen clean, ah those fantastic days when customer service really meant customer service and not a counter where one complained about the lack of service..
