Customer satisfaction!

On Sunday 20/03/2024 I went to Spar to purchase some rolls. There was 3 customers in front of me at the bakery counter. The first left, the 2nd was not attended to however, sometimes preferential treatment and then the customer who was being served was 2 and the teller took for ages servicing them...and I just for rolls had to wait like 45 minutes....when I complained the teller telling me why am I shouting! I rep**** I am not shouting I am talking and haven't got the whole day just in Spar! She and customers she was servicing began mumbling in their own language! When she served me there was no apologies etc....no courtesy from Spar staff....this was very aggravating and frustrating!
