Me: I need an adjustable heater for a qt tank.
, ooooold lady who claims to have been raising fish for 35 years: Ok.
Me; I have an ich outbreak so I need to get the water to at least 86.
Later in the conversation she tells me that all new arrivals get their own personal dousing of Ick Guard, regardless of how they look. I start walking around to find at least two of her tanks are riddled with ich. She's like those doctors who prescribe antibiotics just for the heck of it and now we have MRSA to deal with.
