Stupid Customer - "Hi, I want to pay via direct debit"

Me - "Ok, that's fine, I can see here that you are actually on direct debit payments, so you can just leave it as it is :)"

Stupid Customer - "Um, okaaaaay. So, like, how do I do it?"

Me - "Oh, ok... well, what I mean is, you don't have to do anything. You're already paying via direct debit. You've been paying via direct debit for years. Did you mean you wanted to update your bank account information for your direct debit?"

Stupid Customer - "No, I mean I just want to PAY via direct debit. How do I do that?"

Me - *sigh* "I'll leave a note here, so that's all taken care of for you, we will do direct debit, ok?"

Stupid Customer - "Excellent! Thank you!"
