Went into the Calabasas, CA store Tuesday night and noticed that, before closing, the only place to pay for book/other purchases was through the cashier in the coffee/food area.
Was at the store in Woodland Hills last night and noticed that, like Borders, B and N is staking a fair amount of store space on selling to perceived "hot" consumers. In B and N's case, it's children (whereas Borders in its latter phase was feverish to sell TWILIGHT and other teen-goth romances).
Guessing that B and N will announce more store closings in 2012.
[UPDATE 10/26/11: I was prescient. The B and N at the Westside Pavilion in West L.A. will close by the end of this year: http://www.laobserved.com/archive/2011/10/barnes_noble_westside_pav.php]
