My local B&Q superstore has a lovely big bike park adjacent to the main entrance. The only trouble is, it is completely blocked from access by display sheds, racks of plants, etc. When I complained, I was directed to a sort of portable bike rack holding a maximum of about six, and where you have to lift up the front of your bike to get it in; not the best thing for a heavy ebike! Oh, and it is at the furthest point of the car park from the entrance. So needless to say, on the occasions when I do go there by bike, I lock it to one of their nice plant displays nearest the door.
