Japanese Etiquette Question

[rain_gryphon]

At the little Japanese supermarket here where I sometimes shop, the clerk makes a major display of taking my card in both hands as he bows, then handing it back with another bow and both hands after he's swiped it. Am I expected to handle the card the same way (both hands) as I give and receive it, and should I bow? Does anyone know?


EDIT: Answered offlist (give and receive the card with both hands). Thanks anyway!
