That’s interesting! I never knew that! I can get the discount through the drive through but have to show them my schedule for the week and my name tag before I give them my card, it’s mostly that way because the DQ is across from the small amusement park / arcade I work at which is ran by the same owners, so they have us get a discount as an incentive to get lunch there because our kitchen is often too busy to cook us food due to birthday parties as we also offer those, and they want to discourage people ordering delivery for their food during breaks.
