I've worked in hospitality in my younger days, from around age 15 to 22/23, and can confirm this is true in my experience too. It follows the same MO and power dynamics as male to female abuse and would always be a more senior woman - either by position or age, or both - towards a much young man, often a teenager. Lots of comments of the "oooh, young man!" variety, lecherous remarks about stamina/vigour of youth, having a toyboy, questions about their body, their girlfriend's/relationships, have they ever had an experienced woman, and so on. I have no doubt that there'll have been worse gone on elsewhere but these are the sort of things I witnessed. Basically all of the same pervy shit men direct towards women but all of it still based on power dynamics because abuse is never about sexual attraction, it is always all about power.
