Getting a CharlieCard in Davis Square

Thanks to the T's new CharlieCard distribution policy, there's now a hand-written sign in the Davis T station booth saying CharlieCards are not available.

But they *are* available at Tedeschi's upstairs. http://www.mbta.com/fares_and_passes/sales_locations/?loc=Somerville says 7 am to 7 pm Mon-Sat. Since Tedeschi's is actually open 6 am to midnight 7 days, is that a mistake?
