I do believe they charge for others.

Tesla charging stations charge Teslas free under a charging deal. Other vehicle owners pay. There are companies with charging schemes. It's a business. Did you think it was free?

i wasnt sure, thats why i asked.

im having trouble seeing that business (charging staions) being profitable due to the cost of rent + electricity which would have to be passed onto the customer.

Maybe the 'landlords' of where these charging stations are sited see an earn in passing trade being stuck there charging up and have come to an arrangement of some sort.

Not all Tesla charging is free to all Tesla owners. I am sure your right for Tesla S and Tesla X and maybe the roadster. But I think the Tesla 3 its back to a user pays.

Have a mate with a Tesla 3. It’s stupid fast for a little car.

Free is relative as some one always has to pay. User pays suits me

And FWIW there's little profit in fuel.
Service stations make their money from selling your food and drink, particularly if they have hot food, e.g. fried food take away.

Quite a few years ago an old costumer who ran a road house walled our if his office grumbling.
I asked Martin what was up?
He said that if a customer bought $20 worth of fuel on a credit card he lost $0.20 on the transaction

Profit in fuel isn’t the greatest,at times,but they still do very well out of it.

I know a guy who has 13 garages ATM,and he does very well out of the fuel sales.Plus the addition of the other stuff.

Years ago profits were much lower,but times have changed.

So many questions

Why would a costumer run a roadhouse, not a fancy dress store?

Please explain blue

As an Electrician, I find the KW output he chargers a little confusing to be honest - as per this article, it says up to 350KW for supported vehicles - let’s say we’re talking a Tesla here (we aren’t, but for the calculation) - they run at 375 volts DC. If this was the sort of vehicle they are talking about, that’s a current draw of over 900 amps (I=1000xP/V) where I is the current and P is the power in KW and assuming no losses and flat batteries ready and able to take that current flow - you know what sized plug and cable that would need to be!

I get this would be a peak current and that this drops as the charge comes up, but still, we’re talking about moving a massive amount of power in a short time over a consumer grade connection that has to be able to be used by anyone.

Don’t get me started on the fault currents either and how these are mitigated in the event of an issue - we’ve all seen the video of that Tesla exploding - a very real scenario if your charger’s capable of delivering nearly 1000 amps at over 350 volts - big badda boom as the Fifth Element would say.

So, what sort of current are the plugs and cables actually capable of supplying as I call BS on a hand held plug and cable delivering that sort of current or anywhere near that - anyone who’s tried to connect a 125 amp lead knows this is a struggle on you own - no way a little old lady doing her shopping could connect anything remotely capable of these sort of currents.

Assuming here that the chargers are delivering a DC current and not a 3 phase AC that is rectified on board the vehicle - happy to be corrected if that’s the case (but that’s still over 600 amps at 415 volts with a PF of 0.8...)
