well done tx gas service

The texas gas company that takes care of my natural gas needs has this really neat phone service. You call their 800 number and if you are not immediately connected they tell you how long the wait time is and give you a call back option, i.e. you enter your phone number and name and hang up. Within the time they promised, you get a call back and talk to a live customer service agent :)I am digging this use of technology and not having to stay on hold

I hope more companies follow their lead :)
