Petrol (or gas for you americans)
If you are driving a new car (or a hire car, or a stolen car, or whatever) and you are unsure which side the petrol cap is on, look at the little petrol pump symbol on the dash. It will either be on the petrol gauge or on the low fuel light.

Whichever side of the little symbol the hose is on, that's which side of the cat the petrol cap is on.
