This looks very much like an Australian service (gas) station called Coles Express. $5 is pretty average for this deal which is typically a 600ml Coke and a Chocolate (candy) bar of your choice. These darts look to be added as a joke. I could be way off, but that’s what it looks like to me.
Yeah you’re likely correct I reckon! Still definately feels like a Aussie servo with those prices! 🤣
