Last weekend I was at an airport getting back from Thanksgiving. As is tradition at airports, this meant standing around in the parking garage trying to remember where my car was parked.
I tried locking my car to listen for a beep, but didn't hear anything. However, a nearby airport employee said "I heard it beeping from over there" (then gestured in some direction).
Now, although I didn't know quite where my car was parked, I was certain it wasn't in that direction. I had no idea how to tell the employee that, though. It seemed rude to say I'd rather take my chances than trust them, but I also wasn't too keen on pretending to look over there just to be polite.
In this instance, I lucked out and remembered I was near a certain stairwell, so I said something like, "Oh really? Well I know I'm by stairwell 10, do you know where that is?" They pointed it out (in a different direction), and all was well.
However, I've been in similar situations where I don't have an out like that. Where my choices are to deliberately go against their advice right in front of them, or waste my time pretending to follow it. It's even more awkward when I've asked the person for advice.
How could I tactfully respond in situations like this?
