Went to fill up my car with petrol at barking tescos. Floor cover in at least a bucket of petrol slipped and slid to grasp petrol pump.. Then decided to advise attendant in store of oil spill from previous user. He took offence to being told sand was needed now on the forecourt.. Other staff stood and did nothing either. Went to main store and informed manager on duty. Described incident he walked over to petr station and he and the male attendant discussed how they did not like being to clear up an oil spillage and how rude I was... My husband was standing in the queue and listened to their conversation about me and had to put them right stating that this was serious as customers were slipping and sliding and getting back into vehicles with oil on their shoes. Disgusting disgusting.. Will shop elsewhere and tell all my famy and friends to stop buying from this store...despite my family having shopped with them for over 50 years..
