For folks who aren't from the area, it's important to know the "bad customer service" has nothing to do with your ethnicity and everything to do with cultural differences, especially with the older Apaches. Apaches generally don't smile or talk much except to people they've known for some time. So, if you go in and they help you but aren't jovial or greet you like off-reservation places, rest assured it's cultural and nothing more. Customer service standards are a bit different on the Rez than off. Outright rudeness, though, is still bad customer service and I can honestly say I've never experienced any rude customer service here.
