Unhappy customer

Good day I am very disappointed and feel insulted by a cashier/waitress at steers west coast sunningdale Cape Town. I am a pregnant woman so I bought a meal and there was a lovely lady who served me with respect so I tipped her and she was happy and told one of her colleagues, the response from the lady was “ she has money because she’s pregnant it’s obvious she got money from her boyfriend” please talk to the employers to check who they hire because some of us are sensitive
