This is the 2nd time I have called the City of Phoenix for bad tasting water out of the " Beverage Dispensing Machines" When water taste very bad your just not sure what you're getting. They are not the most cost effective place to eat teriyaki chicken but it's not bad. I think they should have their Beverage Dispensing Machines checked and cleaned on a regular basis as recommended by the beverage company. They should also have some kind of good water filter installed to protect the customers from any kind of contamination. The best way to ensure that the soda machine provides safe, high quality tasting drinks is to keep it clean and well-maintained. Managers need to create regular cleaning schedules and educate their employees in how to perform the necessary maintenance procedures. Or call the company they bought it from and have them clean the soda machine.
