Dairy Queen review: chicken blt salad

This location should be ashamed for the small salad they provide for $6! Bowl was only 1/2 full of lettuce and toppings-- crispy chicken was sparse. Have had much better salads at other locations. What a rip-off! Am I better to complain to this franchise directly- or does Dairy Queen Corporate follow up on complaints? Seems there should be a standard that all locations need to meet. This is NOT acceptable.
