I have been to Tesco Petrol station in Stafford a couple of times this week and noticed that they don't have any ordinary petrol only the higher grade one plus diesel. It's very frustrating to have to drive in to find that all the pumps selling "normal" petrol have yellow plastic signs on them. Why can't Tesco put a big sign at the entrance advising customers that they don't have any? It's strange because it's been like that for a few days. Anyone know what's going on there?
