(I live and work in Iceland.)

Customer: “Do you have international busses?”

Me: *thinking I misheard* “Sorry, a bus for where?”

Customer: “You know, for Scotland or somewhere outside of Iceland.”

Me: “You realize this is an island? You can’t drive to another country from here.”

Customer: “Not at all? What about busses that drive onto ferries that take you somewhere?”

Me: “It takes a few days to sail to the next country.”

Customer: “…”

Me: “So, no. No, we don’t have those.”

Customer: “Not in the whole country?”

Me: “I mean, we’re just one company. You can try asking at the tourist information, but…” *the customer walks off* “…I highly doubt it.”
