Answering a phone call from someone wanting a bed liner installed in a truck, Jason Beard takes the order by clinching the flat end of a mouth stick in his teeth and applying the pointed end quickly and precisely to an iPad. When another customer walks into the Line-X Southeast Customs showroom to ask about tinted windows, Beard rests the mouth stick in one of two holders for these on the desk top of his motorized chair and speaks to the customer without missing a beat. "As technology evolves, I usually get more productive," Beard said.
