Rude and undisciplined cashiers

Cashiers speaking isixhosa when I'm arriving at till point looking at me like I'm sort of talking topic.Even the packer was persistent in speaking isixhosa looking at me.This shop clearly has an Achilles heel when it comes to customer service from their cashiers this behavior was promised not to happen again yet in 2024 we at it again.The cashier was so cheeky she kept my slip from the 1st purchase without my permission so she dont have to engage with me even when I said ill report her behavior she kept on singing and speaking in her mother tongue.I paid for a 2nd and 3rd purchase and she didn't even ask for my Xtra savings card she just kept the slip of my 1st purchase and was very arrogant.All this drama when I took kids to the shop for some things for them and this is how checkers canal walk cashiers behave.
