should i have ordered myself as a flat white?

This morning a walked into the muizenberg branch and as i sat down i was asked to move to a smaller table so that the bigger table could be used by more people. at the time the place was barely 30% occupied and i asked if i could sit there and gladly move if the table was needed. i then found a seat next to the fire place and oredered a cup of coffee. a few minutes later a gentlemen that happened to be of a different race, sat down alone at the very table i was asked to move from...

before i left i told the manager what had happened and she wanted to give me an explainattion i was not asking for... i tipped about 38% of the bill...
