These people hired me to build them a real fireplace, you know hearth fire brick back ,throat smoke shelf etc. So I showed up with all my tools, materials were on route and the wife said “ but you can’t make any dust” I looked at her dumbfounded and started packing up my tools. She said “what?” I said I can’t do that it is impossible no matter what I do there will be dust, so you decide. I built the fireplace with her kicking and screaming and her husband pulling back on the reins all the way
