Bus tubs are used to stack dirty dishes in while bussing a table. Different sizes, colors and styles are available to suit your specific preferences or needs. There are tubs available to store silverware. Busboys will generally stack everything that is on the table and needs to be washed into the tub. Plates get stacked, silverware goes into the glass cups, and everything else gets dropped in wherever it will fit. In order to get everything in the tub without having it overflow or forcing the busser to make more than one trip, you will want to find the deepest tub that will accommodate your business.
