SONIC Drive-In locations in Houston, TX

I have patronized Sonic at Tomball Parkway and Cypresswood for years and have been very pleased...easy access to and from work. Something has really changed in the last few weeks. One day last week I waited in line for 15 min and no one ever answered the speaker. The line was very long and people started leaving. As I pulled out of the line, I could see several people just standing inside! The orders are now wrong...no tots, wrong drinks. Melissa is the one employee who comes out with our orders who is hustling and is trying to correct the very slow service that is inside. She is great! Jessica used to work there about a year ago....she was excellent too! And another thing....I miss the old good Sonic ice! I'm not going to Sonic like I did because of last week's slow (or NO) service. I used to go every morning for a diet coke as I drove to work. McDonalds now has my business, but I would like to go back to my old Sonic that used to be so good. I've noticed that the business isn't what it used to be. I would recommend Sonic to others but not the location at Tomball Pkwy and 249.
