The staff there wants you to pick whatever milk is first in the fridge. I got told off for reaching into the fridge to grab the fresher milk. They just lost me as a customer after spending $60 on fuel over a $3 milk..
Every now & then this petrol station has prices far below those of its neighbours. Unfortunately most of the time it's more expensive.
However, easy to get in/out of, wide bays to park in, and a reasonable shop for drinks/snacks/oil/car needs - and not often busy.
