I have found in personal experience and reading on forums that this is becoming almost a pandemic.
In the past, there would often be times when a family of four would decide to go on, say, Splash Mountain and one of the parents and one child would detour to the bathroom while the other two got in line, then the parent and child would join them. It usually doesn't bother me too much when a group is in line and 1-2 missing people show up a few minutes later, while their group is still near-ish the back.
What ticks me off is when there are 2-3 people in line ahead of me and when we are about halfway through the line, 5-6 people push their way through and cut in front of us. It seems reasonable that if you have a group a few people could get cut off making their way through the crowd or walk slower and get separated by a few minutes, but this is bordering on ridiculous and seems to me to smack of entitlement. I know that during the 24 hour event last Feb. lines were ridiculous and CMs were patrolling to escort people who tried to cut in line to the back of the line and make them wait.
Is there any way to implement or enforce a policy so that if you want to ride as a group, all members must be present when you get in line? I know this would be an inconvenience to someone who is delayed by only a few minutes but it's a case of a few rude people ruining it for everyone else. Is this do-able, or just something we'll have to suck up and learn to deal with?
