Clueless waiter

The guy who welcomed my family & I at the front entrance was friendly & comedic. However, our waiter, Lucas, assumed that based on the colour of our skin, we're Zulu which I found highly unprofessional. The entire time he kept speaking to my partner & I in Zulu. Half the time I had to figure out what he could possibly be saying in a bid to also translate to my family members. Mind you, I'm Tswana & my partner is not even South African so you can imagine the awkwardness. English is both a SA & universal language. If we could please try to accommodate people who dont speak our mother tongue especially in work environments. On a lighter note, their ribs were ok but the chicken was a tad dry...... crisped a little too much. Wonderful birthday environment though.
