I understand that this issue is a sensitive one and there is a great deal of justifiable criticism of tipping culture. However, this comment is snarky. We all know that many countries have higher minimum wages in place of a culture of tipping. The person to whom you responded is not responsible for the prevalence of tipping where he or she lives and there is no reason to be reductionist, accusatory or otherwise snarky.

This is the case in many (most?) states in the US as well.
