Today I visited this specific DQ on NE 4th in Renton (Order ID: AABMDMC8AJDQ). I was CRAVING their delicious Original Single Cheeseburgers, and at their phenomenal deal "2 for $5 Mix & Match" as shown in their mobile app, I couldn't say no! I drove up to the ordering screen in the drive thru, and to my unpleasant surprise, their pricing doesn't reflect what the app shows. The sign displayed "2 for $6" for the very same items in their promotion. I was ready to just leave and go somewhere else. I felt cheated. I was HUNGRY, and had no plans of being deceived in such a disrespectful way today, but here we are. The food was hot, prepared perfectly, had the flavors I cravingly anticipated which danced upon my taste buds proudly, yet was blinded by the betrayal of being overcharged. My soul and wallet weep, and will never visit this establishment again. The staff was friendly when asked for an explanation for the difference, but were unable to provide a logical answer or viable resolution. For shame, I say. Let the records show with the evidence provided, that this specific establishment will squeeze more out of you, when it's already too late.
