Came across this post about gas prices by somebody local. I thought it was just us that couldn't understand the logic of the gas prices, but it seems we're not the only ones.
The prices seem to go up and down at random - one price in the morning and another in the afternoon? And sometimes 10c different on opposite sides of the road. When we've been driving visitors around we start saying things like '72.9', '81.5', etc - they think we're talking about the temperature but we're really reading out the gas prices.
[There, remembered to call it gas so maybe I'm becoming a local after all].
