It happened to me, I was in two BB's near me and they had no clue about the promo and in return I have to explain them everything about the promo and how it works.
I think they don't get any commission for this and that is why they act as if they don't know anything about these services.
Im pretty sure that the sales reps get commissions by the way some members here have openly solicited sign ups.
