With the passing of the years we see everything very differently and although what you tell us was a recklessness, it was also a matter of young people and possibly the owner himself realized it or was told about it but did not say anything, understanding just that, that they were young, or who knows. The good thing is that at the time it did not bring you negative consequences and even if it had, it would have been part of the learning process.
Happy weekend, my friend!
