petrol stations open on Christmas Day

[Sandygay2005]

Can you tell me what petrol stations are open on Christmas Day

[gary baldy]

What? All of them? Where do you want me to start?

In my experience between 50 and 75% of petrol stations are open. Supermarkets are usually shut but small indies are usually open and the big 4 on main roads are almost certainly open.
The best guide is that if they are open 24hrs usually then they will probably be open on xmas day.
