The person writing in said her boyfriend is perfect, except he is chronically late. In the inevitable wrangling post breakup…he said “But you changed your standard” I said…”you never met my standard, and this was always temporary”. If it annoys you, that’s a legitimate way to feel. And with online dating, someone always will! If this person is rarely late, consider letting it slide, but if it is more regular, a conversation is necessary. If his wife was not such an easy going person then his continually grumpy reaction to her being a ‘wee bit’ late could, in theory, start to wind her up, then you would have two grumpy people (‘you are so selfish’ ‘hey but you are so intolerant’) and roll on marital discord.
