Wiping dining tables with dirty floor cloth!

I was always a big fan of KFC, and working across the road from Sandton City, I often enjoyed my lunch purchased from the KFC Sandton City. That is up until yesterday when, as I was finishing my meal - I saw the lady that cleans the shop wipe something off the dirty floors and subsequently proceed to wipe a number of the dining tables WITH THE SAME CLOTH! This was just absolutely shocking - and I can never continue to eat at a franchise store where staff don't have a high regard for cleanliness and hygiene... I can only imagine what gets done with the food! I wont be eating there again as I was beyond put off for - but for the sake of the other customers and general hygiene I hope this gets addressed with utmost seriousness!
