“It tasted funny….”
Everyone with an upset stomach blames their last meal, and some are right. But the toxins that make you sick quickly (mostly staphylococcal) and the bacteria that made you sick after a few days (salmonella, shigella, campylobacter) have no taste.
“My pressure is up.”
Calls from guests to “check my pressure” arrive regularly. I can’t remember a visit in which high blood pressure was the problem because high blood pressure doesn’t cause symptoms. I won’t mention the symptoms it doesn’t cause because no one believes me.
