Yeah... occasionally they get competitive on fuel prices... but I guess when Certa was the main competitor as far as fuel is concerned folk would still pop into Applegreen for a piss and might buy food/drink while they're at it. I see a lot of men with large appetites loitering on their forecourt while waiting to pay extortionate commission and car parking fees for Free Now jobs from DAP. That can't be bad for business.
Indeed, SB... I'd guess it'd be mostly corporate clients that couldn't give a flying fuck about the price of fuel that wouldn't bother filling up.
