Extremely poor service

I am so annoyed by what just happened to me at exactly Sunday 31 May 2020 @9am Spar hillbrow highpoint whoever owns or manages that place train your cashier's especially the one at the till where we buy electrify. She gave me a very rude approach as I'm typing I'm still waiting for her from her tea break to come and serve me. She rudely said to me "are you going to wait for me for 30 mins" the fact that that's the only till serving electricity leaves me with no choice but to wait for her. I hope she learns the definition of customer care. And that customers are not beggars they the ones who pay your salary. We are blacks yes but that doesn't give her the audacity to be rude. There are millions who would die to have that job. Kindly contact me I'm ****ed
