Sit in P2, but for many years sat in P5 and it was always littered with them, I'm a sado that I like to monitor home ticket sales and how quickly they go, Arsenal, Liverpool, United, not so much Chelsea literally fly and a few at most make it to booking history only
All the other teams, including Man City plenty make it to booking history only with plenty of availability in Upper Doug & Trinity
I would like to think its a case of many of our own fancying it, but like others have said its blatantly other fans buying up tickets. Over the years with how relaxed it is in the Upper Doug, even when fans make themselves known most just turn a blind eye, the one year I mentioned to a steward about a United fan celebrating a goal he had a word and came back and said the fan in question was showing his frustration they had conceded. I guess (understandably) for what stewards get paid they don't want the agro, but it is frustrating.
I don't know how you stop it though, I read a post the other week that 2 United fans had paid 3K each to be in the away end at Newport, if people are willing to part with that sort of cash £68 in the middle of the Doug and what a £40 membership isn't going to deter
