Work event yesterday, lots of drink and dance. Senior manager, married, late 30s/early 40s in the thick of the dancing, noticeably paying lots of attention to the younger attractive women but nothing too untoward. Afterwards about 20 of us head to another venue, he is very much the worse for drink, barely able to move, and rather more touchy feely with the youngest most junior and member of staff who comes across as very young and not at all streetwise. She didn't look too bothered, nor was she especially encouraging, she was just dancing. However, I felt uneasy and I felt relieved when he left separately before she did. Another man in the group commented on it, so it wasn't just me noticing.
Both people are adults. It was mostly after the official work event.
