Spar Soshanguve Crossing shameless service

I went into Spar Soshanguve Crossing to go buy food for me and my daughter today on the till there is a cashier called Naledi a light skinned lady who is very slow and has no regard for customer service. We waited on the que for 35 minutes, every customer that she assist she would call the supervisor to come and void some item. That Spar has about 10 - 15 tills which doubles but there is only one person working there. It's month end and as expected the ques will be long but please use young people who are energetic and willing to work. The service is very poor especially at the tills area.
