Poor service from Marcia

Today I did my shopping at Mr price festival mall. Well I went to this cashier by the name of Marcia. When I put my clothes on the counter, I greeted her first and she kept quiet. Well I thought she didn't hear me. She then spoke to another colleague of hers on the next till in Tsonga language telling her about what happened yesterday. She never even told me to insert the card. She just turned the machine and I had to insert my bank card. After she was done she gave me the receipt and never said anything. I then asked her if she was tired and she said yes. I asked if she was sick she said yes and I asked her why she doesn't ask her superiors for a day off to go to the doctor but she said ahhh
