Reply #47: It might be a Texas thing

I have noticed here that a local hamburger chain does not put ketchup on its burgers- you have to ask for it, unlike national chains like McDonalds. I have also discussed this with people I work with and they don't put ketchup on hamburgers either. To me that is weird. Ketchup (and mustard) for hamburgers along with other toppings and mustard for hotdogs or brats.
