Day 79 {Only in the north}

Only living here would I come across a sign like this

Not sure what the purpose of this is.......there are three other full serve gas stations within  a 3 minutes drive that pump your gas ALL day ANY day

And I should add for the same price if not cheaper.

But hey if you are at the store on a Tuesday between 9 am and Noon somebody may or may not come out to fill your tank for you.

Thanks for looking :)
