The Tempo Grab & Go is not selling the mugs, because last August before it closed a manager of the Food & Fun Center told me that location will not have the equipment for a soda machine which is why. So once Chef Mickey's Express opens they will have a soda machine and will go back to selling the mugs.
Also it's nothing new for the temporary counter service locations not to sell the mugs, because that's what happened when Captin Cook's and Roaring Forks were being renovated. The temporary counter service locations at the Polynesian and Wilderness Lodge did not sell any mugs.
