If I say “you can use my car for $250/month if you don’t smoke in it” and then you pay me that money and you drive around until one day you smoke in it, I’m not going to let you smoke in my car. I told you not to smoke in it and you smoked in it. That’s the deal. All seems fine to me tbh.
I think it's a bad analogy. For one - smoking does very high permanent damage to a car interior.
Two - the usage pattern was Shaun's toc but not obviously against the spirit.
More like "you can use my car to drive around as much as you want" And then going: Obviously I didn't mean driving to another coast on a highway
