Ssssshh, we can't tell when we're open

I'm currently emailing various stores asking for lists of their opening times where this information isn't presented on the website. So far this is the best response.

As all [name store removed] stores are Independently owned I am unable to provide due to the data protection act.

On a related note, I've submitted a Freedom of Information request through WhatDoTheyKnow, to the Post Office asking for a list of the locations and opening times of their branches. So far they have refused, saying the information is already available through their branch finder service, however I'm disputing this as compiling the results would be very tricky.
