basic search engine failure

Why is it that 14 years after search engines took off, and millions of pounds of research later that in 2008 you still can't do something as basic and necessary as typing in your postcode to find out where the nearest chemist is that opens on a Sunday?

Even the NHS don't publish this info online, yet somehow they manage to give it to their contact centre staff. Staff who require to know your name, address and date of birth to answer a query.

How is this data collection justifiable when the information should be freely available online?

You can't search for post offices open on a Sunday either!
