Rip Off Tesco

Had another migraine today so not feeling at my best.  Did a zombie walk to Tesco at lunch and was just about with it enough to stop and blip.  The cost of petrol hasn't gone down past £1.43 a litre for many months, despite many other garages in the area being up to 10p cheaper.  Think this person was fed up, though being in close proximity to the motorway I think it will always be a bit of a rip-off though I do admire and impromptu protest.
