So what? Automobiles are meant to be driven. A car dealership doesn't ask you to leave if you told them you were going to purchase the car and put it in storage and never drive it.
I'd say any company that asks you to leave their business because you were considering using a water bottle for a fuel bottle is a company that should be out of business. They could explain to you why you should not use it for a fuel tank but asking a customer to leave is very bad business.
problem is that in the land of lawsuits if i would suggest that you can put kerosine inside a nalgene waterbottle.
some idiot will put kerosine in and drink it , and sue the guy who said that it was possible......[X(]
