On that basis you could argue that businesses shouldn't have to bother about making their premises accessible to wheelchair users, or to work to accommodate the needs of blind or deaf customers, and that supermarkets shouldn't designate quieter periods to make life easier for people with autism. Fortunately the law now forces many of those adjustments upon businesses but should individuals need legislation before simply adopting a bit of common sense and consideration?
Some time ago a nursery school in Stowmarket has a prominent sign on the door, advising all visitors (whether parents of children or delivery staff etc) that entry was strictly banned to anyone who, for example, had recently used a nut-based shampoo on their hair. That was due to a child with an extreme nut allergy having a place at the school. I'm sure that everyone who had any form of contact with the school took great care to comply with their rules but, using YMB's logic, it seems that the child should never have been allowed on their roll in the first place!
