Four times a day? That is not a house, that is a greenhouse fogger on a timer. I am not surprised your fern fried in a day or two because a plant raised in that kind of wet air gets spoiled fast. The minute it hits normal room air and a sunny window, it cannot keep up. What gets me is the owner just told you the truth after the fact, like that fixes anything. A shop should tell you what conditions it was raised in before you pay, not after the thing is brown. I would bring it back and ask for my money, because no one can copy a misting schedule like that at home.

The HEB on Mueller has a sample guy who gives out tiny cups of salsa and I watched a woman ask for 9 cups in a row, saying she needed to compare heat levels before buying. The guy just kept handing them over with a frozen smile. I finally said loud enough for her to hear that the salsa was 2 for 5 bucks and she grabbed one jar and left. Next time just buy the cheap cheese and hand it to the lady, that works better than the gruyere move.
