This reminds me of a support call I took from a customer based in Texas. I was trying to make an appointment for her and, not knowing anything about her tiny stupid town in Texas, I asked her what time zone she was in. Her: "I don't know...Texas time." Me: "Well, Texas spans two time zones. Are you central or mountain?" Her: "I don't know. Why do I need to know that?" Me: "Are you in the western panhandle?" Her: "NO!" (like I'm some idiot) Me: "OK, for future reference, you're in central time."
