Not Shell like it used to be. Difficult to tell as pump colour is similar. Typical motorway services customer rip-off!

Extortionate prices for fuel and shop items. Charging almost £5 for a bag of starbursts that are around £2-3 at other stores! However, often have very friendly staff on and have tasty coffee!
