Especially, since on mobile phone "bootlegs", you usually can neither see anything, nor hear it clearly enough to discern the music from the crowd noises around you... those people are a waste of good concert space.
But in other news: either it's me getting older and grumpier, or the young'uns seem not to be able to behave properly at concerts/festivals:
Back in my days, when we moshed and pogoed, we'd form a moshpit and tried our best not to bump into those not inside the moshpit, with occasional apologies if we didn't manage.
Nowadays, people like to form a wall of death and run at full speed into the backs of people in front of them, and generally pogoing at anyone in the vicinity. The last contcert I attended, I could only save my girlfriend from being bumped by some big guy by ramming my elbow in his face just before impact.
Also, back in my days, peiople attending festivals were like a big, happy family, with very little brawls and next to no stealing.
Nowadays, everything you leave outside of your tent is a goner when you wake up. And your tent is covered in piss.
That's why today, I don't enjoy it anymore to go to festivals and concerts that are bigger than 200 people in the audience.
And I've definately become a grumpy, ranting old and bitter man. But then, I am approaching 30...
