Santa Rosa, CA fails to allow any of the popular national Sonic promotions, i.e., 1/2 price slushes, limeades, between 2-4 or the 1/2 shakes after 8pm. They also advertise the app on their menu boards and then fail to honor the discounted app prices, "saying it's a 3rd party and not affiliated to that franchised Sonic." The Santa Rosa location is a very negative representation of the Sonic Drive-In Brand. This location is a very negative representation to the SONIC Drive-In BRAND, and their business practices are deceptive to the loyal Sonic Drive-In customers! We have had decades of positive experience with SONIC Drive-In's nationwide. We have given this location several chances being new; the staff and management are just rude. It probably explains the drop in local community enthusiasm for this SONIC brand. It's truly unfortunate, customer can travel just a block in either direction to other fast-food locations with far better customer service and products.
