Bad example, but in concept, yes.
It’s a bad example because we know full well that football is muttar (unless you want to kler maybe tackle football is a sakana…) and that recognized poskim have allowed and encouraged participation in sports (at least in chutz la’aretz…).
However, a psak that tipping is mandatory when it is the norm is fully consistent with regular dinei Choshen Mishpat cannot be ignored unless you have a psak otherwise.
