Commercial uses of bendalloy and cadmium mistings (inspired by Brandon Sanderson's 'The Lost Metal')

Edit: Some context if you're unfamiliar with mistborn: A bend alloy misting (slider) can create a bubble where time moves faster. A cadmium misting (pulser) can create a bubble where time moves slower. These bubbles can't be moved, unless they're on an object of significant mass that is already moving, like a train. The civilisation in The Lost Metal is roughly in the industrial age.

I was reading "The Lost Metal" and the newspaper ad after chapter 2 mentions hiring bend alloy mistings for a fast food restaurant. And I was thinking of more commercially profitable uses. Because fast food, wouldn't (I think) have sufficient margin to support consumption of bend alloy which is supposed to be expensive. So here are some ideas I had:

• One idea I had was a CEO using a bend alloy misting to give them more hours in a day. Time for CEOs is already at a premium so giving them more I think would be economically worth it, but I don't know if they have anyone comparable to that in mistborn era 2.
• I also think this would work for lawyers. I'm not sure how much a lawyer in Elendel gets paid but we do know they exist. In the real world sometimes lawyer bill for more than 24 hours a day (illegally)! But imagine if a lawyer could do that legitimately now. Maybe even 48 hours in a day!
• An idea I had for cadmium mistings was to speed up travel. Maybe for rich people you could use a slider to get up time so that their train journey appears to them to go by really fast. But that might be counteracted by their circadian rhythm getting messed up.

The following links contain some discussion on the usage of bend alloy and cadmium for commercial uses.

Some ideas mentioned there include using a slider in the waiting room of a hospital, or to preserve food, or to reduce the amount of food needed to support a siege, or to reduce the amount of supplies needed for Interstellar travel.

What are some other ideas you have for how a pulser or slider could be used during that time period in a profitable manner?
