Wrong Directions

I've spent the last few days wondering if I should be obligated in my off time to helping people traverse this fair city. It's not often, but not seldom either that I find myself at the wrong end of a string of questions amounting merely to "where am I?"

They list landmarks, streets or restaurants they've noticed in the few days of waking life in St. Louis and hope that I would be able to direct them to the nearest washroom or transit station.

While I haven't yet had time to setup a google map of all the public urination solutions in St. Louis, I have a fair knowledge of transit stations and the respected destinations.

However in many instances I'm off the clock, it's past my workday and I want to go home to watch PBS, I have a penchant for roadshows. I could sit down and draw these people a map using the landmarks they provide, but am I obligated? What heavenly body governs moral nicities?

So what is worse, what will lose me more points in translation; lying and saying I don't know where you are, or sending them off on their own journey? Who knows the later might find the questioning knowing more about geography or transit, perhaps I would've taught them to fish.
