Cashier leaving me hanging

You should really teach your cashiers some manners... Went to PnP today to buy a couple of things... Got in the queue and got to the cashier and started unpacking my trolley... Without a word the cashier got up and walked away leaving me and my trolley at an empty till... I decided to just leave the store and not cause a scene and on my way out, my wife and I walked past the cashier who just gave us a very nasty look... Anyways... Went to Spar and got everything I wanted and for much cheaper. Guess I will be visiting the Spar more often now, much easier to get in and out at the Spar in any case, no traffic jams due to the parking bays in the street... I am just shocked at the level of service, because the service at the PnP used to be good...
