To be clear. They were cleaning them for the next buffet. They were cleaning them on the floor. They did not go to the kitchen for cleaning. Once they were done cleaning them with dirty rags, (also used to wipe the floor) they reset them up on tables for the next buffet and rolled the tables with these buffet servers back in the corner or another room for usage on the next buffet. It was apparently the "Final Cleaning" as they were set up on tables with clean table cloths with the napkins through the handles and on tablesfor the next buffet and the tables all set as they would be for a buffet.
Of course we could recognize if it was a "first touch" before the kitchen. My point is that the Management should be more observant as to cleaning of these silver buffet servers and good sanitary procedures.
