Not sure why you labelled my comment "strange", we clearly worked in different types of workplaces, as it was the norm for this to happen in the industry I worked in (I didn't know this prior to getting the job at only 16yrs old), and there was no such thing as an HR department where I worked, so there was no one to report any male staff to.
However, I actually did speak up against the customer groping and had a number of customers barred from the establishment. So do not assume that I "shut up and put up", as I did not when I had the option to. So do not attempt to shame me, who was a 16yr old introvert girl (under the legal age in that country), unfamiliar with this type of behaviour, having come from a very religious household.
Nor was I thinking my experience as "impressive", gosh, what a disgusting insinuation. Clearly they have impacted me, otherwise the experiences would be long forgotten. I made my comment because these days it seems that people are reporting to HR the silliest of things, when actual sexual assaults were commonplace in many industries not that long ago.
A "stuffing your face" comment is more likely to be banter than anyone actually trying to shame OP, and it's highly unlikely her manager knew about her food issues. So he didn't say it maliciously, he just inadvertently put his foot in it.
