Yeah, I don’t know if it’s still true but years ago basically the cost for the cup and straw for the business was greater than the cost of the drink itself.

So if anything bringing my own container would save them a good chunk of the cost of a fountain drink.

I will say as someone who lives in a cold climate, but that typically likes cooler warm air. It would be nice to sometimes be able to set how cold the air is coming out of the vents and not the temperature I want the cabin to be. But other than that, yeah I think my Honda Civic handles this pretty well as well
