Stop eating dairy queen hamburgers

I have gone to dairy queen over a dozen times in the past year to buy their hamburgers and I'm very dissatisfied with their burgers. The quality of their burgers have gone way down since when I grew up eating their burgers 55 years ago. I have noticed a huge decline in the quality of their hamburgers with regards to the taste and the way they are cooked, which is not to perfection anymore. The burgers I get are normally charred and tough and not to mention the staff employed there are very rude and have no customer skills at all. Good bye to one of my favorite places. What happened to you over the years? Even you ice cream sundae selections have changed with very little variety.
