Some of them are such busy places that queues are often out the door in my area, and it's funny because it has an automated entry door.  It's amusing watching people deal with the door when in the queue.

Anyway.. half the people at POs seem to just wanna pay a bill which can be done online in a minute.  I wrote to AP about eight years ago suggesting they setup a self-serve pay station for bills and they thanked me for the suggestion.

I read last year that they are now trialling them in some stores.  I've never seen one though.
