I have always found it odd when wandering around Sainsbury's picking up my high carb, low fat groceries seeing people shopping still wearing there helmet worn to cycle to the supermarket. Now, I sometimes shop on a bike but I always carry tde helmet under my harm or put in the basket out of the way. Bright yellow tops as well look out of place under the bright lights, I would take mine off and put in a bag or something.
Last week I got the train to London and while waiting to leave my seat I saw a chap walking through the carriage wearing his helmet. I assumed he was walking through to collect his bikes but a couple of minutes later I saw heading down the escalator, no bike and still wearing a cycle helmet. Felt like telling him to GET IT OFF!
