I did my early morning grocery shopping run today and the entrance to the supermarket was blocked by a massive queue of motorist waiting to get into the petrol station. The entrance to the garage is also the entrance to the supermarket, so I broke the law, overtook the queue and entered the supermarket by the exit gate. Panic buying of petrol everywhere, although on my way home a smaller garage only had a few cars in it. My local one has closed all its pumps. I have over a half a tank and that will last me several weeks, so I will not be joining any queues.
You British would probably think that going to a gas station meant to dine in a Mexican restaurant.
petrol (UK) = gas(US)
If you lived in a caravan, you would visit a gas supply shop
