Diabetics everywhere be aware. Although I agree all staff were very polite . There is one thing that people need to know. I went for my diabetic eye test during which I suffered a hypo none of the staff in vision express had any knowledge or experience concerning this very serious illness. I even check with the Tesco manager who also did not understand about diabetes. I had a 7 mile journey back home and only just made it . I feel if any company is offering diabetics a service there staff should should be educated regarding this serious illness before someone dies.
