Horrible service from the rude teller

Spar Barclay Square must take its staff training. i was assisted by a rude teller by the name of Carol on the 16.03.2018 at 17;19. luckily the owner Susan was there to shop as well. I informed Susan of the rudeness of the behavior and she did absolutely nothing. continued to shop as if nothing had happened. i am highly disappointed by the service from the teller and the response from the owner. This is the worst Spar i have ever been to by far. service and all
