Want a Dunkaccino with your deposit? Bank at Dunkin' Donuts

It might be the ultimate early-morning eye-opener: imagine stopping in Dunkin' Donuts for a morning coffee and opening a checking account at the same time.

It's not a far-fetched scenario, as Citizens Bank this month opened the first full-service bank branch in a Dunkin' Donuts shop. And if the venture succeeds, the bank says it may roll out more partnerships with the breakfast-treat chain.

Citizens, which is owned by the Royal Bank of Scotland Group (RBS), opened the branch this month in Bellingham, Mass., a suburb southwest of Boston. Part of the bank's strategy is to provide banking beyond traditional hours, with the Dunkin' Donuts branch open seven days a week and from 6:30 a.m. until 6 p.m. on weekdays.
