Couple years ago I was having a trip and driving my 350z(at that time) to Boston from Toronto, so it is a 9 hours drive and I took off at around 12:00am so I'll arrive in the morning.
About half way I have to feed her so I stop by the service center and give her a full tank. So I fed her the gas and when the pump stopped, I saw the price on the display was almost $20 less than what I usually pay in Toronto.
I was like, "mmm.... the pump stops too early, it's not full yet......", since it is in gallon, so I have no idea how much gas I have put in because we use liter in Canada and it was 3am in the morning...
I tried to pump more gas in since I thought the tank wasn't full yet... then eventually realized the fuel price in US is just fricking cheap!!
