Touching someone's leg surreptitiously under a table implies that he knew what he was doing was wrong and had sexual connotations. But even if it wasn't, it was unwanted attention that some men feel is their God given right to enact. I think a lot of comments on here stem from the 'it was acceptable in the 70s' mentality. Well, it's fucking not ok now, nor should it ever have been.
It's all very well saying to a woman 'well if you didn't like it why didn't you say something?' But countless victims of rape and sexual assault report that they "froze" and blamed themselves. What an abhorrent world we live in where silence is deemed to be consent, even by other women!
I was at a pub on Saturday, completely sober, enjoying a night out with my sisters. One of the men repeatedly kept coming back to our table. He was friendly enough and my sisters were chatting to him, there was nothing overtly sexual in his behaviour. I was a bit more reserved, because I'm naturally more cautious anyway, but also because I'm heavily pregnant and was feeling a bit self conscious. I absolutely gave him no indication that I was in the least but interested in him, or invited physical contact, yet he still sidled up to me and put his arm around me. I didn't tell him to get off, but I'm pretty certain I must have visibly shrunk away from him - he took the hint thankfully. I'm normally quite assertive in many aspects of my life, but not on this occasion - I didn't want to cause a scene and was worried that he might react aggressively because he'd been drinking. I was actually a little afraid, partly because I'm particularly sensitive to being heavily pregnant and feel vulnerable (I was sat down and he hadn't noticed). It wasn't an overtly sexual pass, he may well have been just being friendly, but i felt uncomfortable and didn't want it. I was so angry that the assumption is that silence gives someone the right to invade my personal space like that. I didn't know him from Adam and had given no signs that I was enjoying his conversation or that we'd become 'friends'.
Seriously, when did people become so oblivious to body language that they can't tell the difference between an invitation and unwanted contact, whether sexual or not?
Op, in all likelihood I wouldn't report it to the police. But I probably would report it to his employer, especially as he has 'form' for it. He may never have jumped across the line with both feet to your knowledge, but his behaviour indicates that he certainly has a staggering disregard for personal space at the very least.
