'Mobile kiosk' could build brand awareness, and hopefully volumes at the 6 Washington stores which are desperately in need of revenue, as BCCI is losing money at a rapid rate (BCCI financials show operating losses of $0.63 for every $1.00 of revenue, with an additional $0.30 of cost for interest expense).
As a side benefit, it can provide employment opportunity for the Grounded in Seattle girls while they wait for a major network to pick up their show.
