They're different types of plastic. A jerrycan is much thicker than a plastic bottle. The petrol could eat through a thin bottle.
I was wondering why the cashier sold it to her but maybe they didn't see the container, didn't know it wasn't safe or just weren't bothered getting into a conversation with someone obviously behaving very strangely.
It is strange, they're usually hot on things like this 1, because of the sheer stupidity of some people and 2, the amount of people who chose to "drive off" with out paying., obviously shes not in a car but even so.
They're usually straight on the intercom if they so much as see you with a phone let alone looking as suspicious as this with a plastic bottle

almost gave me a heart attack. And the awful boss used to try and force us to pay out of our pockets for any money lost to people filling up and driving off without paying. For that alone I used to be ridiculously cautious and diligent when authorising a pump.
