I had an older lady call me to ask why I had been calling her phone. Had to explain that scammers were faking caller ID numbers, it wasn’t me, and everyone was dealing with the same garbage phone calls. She was initially ready to chew me out, but deflated pretty quickly when she realized her vexation would have to be vented toward someone else.
Also called Bitrex, that stuff does leave an awful taste. Gets used as a denaturant in ethanol to keep people from drinking it. Company I worked at long ago had a stock of it, and our lab had to requalify it for use every 2 years. As careful as we were keeping it contained, it had a way of spreading everywhere. For the next two days everyone who worked in the area would randomly get that awful taste I their mouth.
