New layout at Post Office: accessibility thoughts

My local post office has just introduced a ticketed queuing system. This is a lot more convenient for me, because I can sit down. There is now a block of seats to navigate around, where there used to be a chicane defined by ropes, so I assume this is easier for people in wheelchairs: more space, nothing knockable-over (the entrance is step-free with automatic doors, which look wide enough to me). I don't think the touch-screen take-a-ticket machine would be in reach of most wheelchair users though. There's a tannoy and a visual display, but the "Ticket no. xxx go to window w" doesn't stay there very long; but if your number's reached the front of the list on the screen and you missed it, there's a display over each counter which alternates the window letter with the number they're looking for. It's a new system and they still have someone there showing everybody what to do, and a big sign with instructions and "wheelchair user", "blind" and "deaf" symbols saying "ask for help if you need it". They clearly assume blind people will either have somebody with them or ask for help anyway, what with the touch-screen and the purely visual counter identifiers, but I think it's an improvement for anyone else, as long as you can operate the ticket machine. It's definitely better for my hips, or whatever else hurts on any given day.
