Petrol from grocery shops

I discovered that here I can get petrol for my motorcycle from the grocery shop. Just ask any grocery shop and chances are, they have it. Therefore, not necessary to go to the petrol station which can be few kilometres away. The nearest is I think the Petronas station in Sg Buloh. There's another two Petronas station in Puncak Alam and there are two or three petrol stations in Ijok. Two days ago, the petrol in my motorcycle tank was so low I worried if I can get to one of the petrol stations. I heard before that some of the shops in the kampong sell petrol but I was not sure which. Stopped by a motorcycle workshop to ask. That's when I was told the secret.
