I got there at 17:20 on a Friday (advertised closing time is 18:00) and all the cashier desks were in the process of closing for the day. The only person I spoke to was the girl at the reception desk who told me the tills were closing for the day. When I told her all I wanted was to change my address so I just needed to complete a form and have them process it she said she didn't know if they had any copies of the form already printed and that I should just download it from their website myself and come back the next day.
