"We didn't have so many warning labels when I was a kid, because people weren't so stupid back then"
However, if you actually stop to think about it, the converse is actually more likely.

In my experience, you only need to warn about something after someone has done the thing no-one thought a right minded person would do.
Interesting thinking ☺
Although I actually think all the warnings are because of just one thing - lawyers
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
