Never Coming Backflow To This Place

(I am cleaning the lobby in the theater when a female customer comes out of the restroom. She goes to use the drinking fountain. As with most businesses, the restrooms are located right next to the fountain.)

Customer: *aghast* “This is disgusting!”

Me: “Is there something wrong with the tap, ma’am? We do clean it often but I haven’t made it over there yet this round.”

Customer: “No, it is lovely. You do a fine job. It was just horrible!”

Me: “If there is nothing wrong, why was it horrible?”

Customer: “Because when I was drinking the water, I heard a toilet flush in the restroom and it made the water pressure go down!”

Me: “Well, yes. The plumbing is connected as they both draw from the–”

Customer: “That water that I was drinking? A minute later, if I hadn’t come along, it would have been used to flush someone’s waste? That is so disgusting! I can’t believe it!”

Me: “Well, would you rather the water pressure went up when you heard the flush?”

(The customer takes a step back and looks confused. Suddenly, the implication of my statement reaches her nearly hysterical mind and she flees the building with a look of horror on her face.)
