Today I was shopping with my mum. She wanted to buy paracetamol and hay-fever tablets and I needed ibuprofen, two packets of each. When we got to the till they refused to serve both of us. Either one or the other, saying as we entered the shop together we couldn't both buy painkillers or the shop could be fined £1000. Never had this before but went along with it and mum purchased her tablets. Went along the road to a different store and both purchased two packets of ibuprofen without issue. Anyone know which shop was correct? (Note: we aren't misusing OTC painkillers - I am recovering from spinal surgery and mum has chronic pain from back injury and a recovering fractured shoulder.)
