It's a nature thing...

Got in a bit of a twist up with a client the other day because he was going to hike into the forest south of here to fish in a lake.  Problem was he took offense to me suggesting it was unsafe to go into the woods with winds gusting to 50 km/h (said I was 'restricting him). Perhaps it is uncommon for a proprietor to look out for the safety of his clients;  I just know that locals get dead quick when a tree comes down on them.  People compulsively check phones and expect weather reports to be accurate to the hour, looking out for rain.  How could high wind be inconsequential?
