So sorry to hear about that. I've had similar, but not that bad and not all at once.
At WAoVW, in the front row nonetheless (center!) this guy took off his shoes and had his feet outstretched for practically the whole show. I mean, what do you say? "Excuse me, but can you please put your shoes on? You're exceedingly tacky." He was w/ a woman FWIW who had a box of Godivas she was eating during the show (she was quiet though).
That was bad, but this mortified me. During Doubt, again front row center (across the aisle from me), this guy had his feet outstreched ON THE FREAKIN STAGE FOR THE WHOLE SHOW. His feet were pushed up against the ledge of the stage, if that makes sense. I was DYING. I seriously wanted an intermission so I could do something about it.
Then there were the loud drunk girls behind me in Chicago who sang along. Yep that was fun. The whole audience shushed them but house manager did nothing. They were LOUD (and rude); someone (usher, someone) would have noticed but they were not removed.
There are more stories, but those are doozies.
