R. is still trying to figure out this exchange at the gas station:
Tankwart: Would you like a coffee with that, sir?
R.: Nein, danke.
T: How about a coupon for a donut with a coffee for the next time you buy gas?
R. No. I'm probably not the Zielgruppe for coffee here (meaning: I never buy coffee at the gas station because I am too frugal).
T: Ach, so alt sind Sie doch nicht. (= oh, you're not all that old, Sir = uhh? what?
