Honestly y'all. There is just as much self importance coming from those who refuse to let people go past them in line as you are spewing at those who admit to doing it.
I don't disagree. My time is important.
Your time is important (general you.) So, if I need to join a line, I get at the end... and wait. If someone needs to use the restroom, we wait until they're finished to join the line. Because it would be simply unfair to other guests to shove past them in line. I'm not asking anyone to give me special treatment... just to join the line with their party.
For the record, if I see a parent and small child leave, I am more than happy to let them return. That is a
vastly different circumstance than when Mom, her two kids, aunt, uncle and baby cousin push up 45 minutes into a 60 minute wait to meet Dad when we've never seen them before, because Dad acted as placeholder to a family. There's a huge difference between "stuff happens" and "we sent someone ahead so we didn't all have to wait" and "it wasn't worth
our time to wait for our entire group to be ready, so instead we're going to inconvenience
your group by shoving past.
BTW... the "pushing past" is as much of an issue as the "cutting" for some people. Lines are not designed to have folks passing other folks. That's why they're narrow, and walkways are wide. For those of us who may have "personal space issues" it's more than an inconvenience to be pushed past, have toes stepped on, be smashed against rails etc... all because someone felt their time was more important than that of those around them.
