That depends.
If your feed is I independently fused, ie the fuse to the 16a socket has nothing else off it, then you should be ok. But if he has other things off this circuit, then you might cause him issues.
You have just dropped in the fact that you are setting up your Chuck wagon next to a petrol station.
How close are u to the pumps and petrol storage. That might be the bigger issue.
Im about 30m away from the pumps etc, down a 10ft ramp with 2 building between us. Its just they have a spare connection at the side of their building on the way down the ramp.
