I learn a lot from this show and it help in my building maintenance job. i like this about the regulator on gas meter but for the cut away I know it had to be that way but Richard could you have mentioned that there was a vent on the regulator. I had a coworker ask me to check the vent and make sure it was clear, but from your cut away and no mention of a vent in the demo I didn't know there was a vent on the regulator so for next time there may need to be 2 cut aways explaining what the meter is and how to be safe.
I was a painting contractor for many years and never asked for a deposit upfront. A good contractor should have great credit with his suppliers and an even better contract if the deal should go south before the job is done. Get to know your customer and explain how each paint covers so they understand fully before you have to apply 3 or 4 coats. If you didn't bid your job right and the client has already signed the contract then that is on you not the client. Yes I haven had to eat the difference but the client was happy and a return customer for years so I made up for it.
Maybe you've just moved into a new home, and you haven't got around to buying brushes and rollers yet. Perhaps you're worried that your brush-skills aren't that good, and you won't achieve that professional-looking finish that you’re really going for. Handy professionals will turn up with everything they need to get the job done, from ladders and brushes, to rollers and tarps. You just have to provide the interior paint and primer!
