Dairy Queen

Our family has been going to the Dairy Queen location Jamacha. In El Cajon, California for years. Although the owner and small staff are polite and helpful, it's Always HOT inside this location. The door is always open and feels like no air conditioning is on never. Especially with this recent heat wave we've had here it's upsetting that we want to have ice cream but can not deal with the lack of air conditioning at our Dariy Queen. Therefore we've gone to a different ice cream place. Is there anything Dairy Queen corporation can do with this location and the air conditioning issue.
Please help :(
