What Non mopar mechanic work are you doing

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
How do you say DUH!!!
My neighbour had their garage floor (24x24) poured yesterday and then coming back today to cut it.
He asked if we were going away tomorrow to which I replied no. He said there will be a lot of dust but will wet it down as much as possible. We'll definitely be closing the windows and garage though.
