Fast food- Ever seen maggots in the soda dispenser spouts?

I worked on fountains for 40 years. Your friend is mistaken.If the nozzles aren't cleaned weekly they can build up with a black crappy gunk but no way could maggots be in them. If there were it would flush them out when the valve was run.All the fast food places I have been at take them off every night and clean them. Some convenience stores let them get nasty As far as checking them your self i'm sure they aren't going to take them apart just to show you. I guess if you are worried you need to buy soda in the bottles.
