Remember the popular saying, if you drink, don’t drive, if you drive, don’t’ drink. That rule is much easier to obey now that petrol and some brands of beer now sell for the same price. You know your beer brand that goes for the price of petrol.
So, you can now chose to buy fuel, drive and not drink or buy your favourite beer and not drive, just walk.
That way, you need not think about breaking the rule.
