Several of you have reported that your local Quiznos store wasn't too cheerful in accepting the free sub coupons offered on the corporate Quiznos web site earlier this week as part of the chain's "Million Sub Giveaway." Across the country, some franchise locations have even refused to accept the coupons. I don't think Quiznos realizes the damage they are doing to their brand by not having their act together on this promotion. If they are offering free sub sandwiches, individual locations should be cheerfully handing them out. If Denny's was able to pull off a nationwide free breakfast promotion with so few glitches a few weeks ago, Quiznos should be able to pull off this promotion without making so many people angry. What are they thinking?
