We have one that did that as well.
Still, After paying my bills I have more disposable income than most flight attendants. Not to mention the fact that I would be in the same situation as others here. Although I'd probably punch the small child too. I don't know how flight attendants do it. This is one of two jobs at an airline that I haven't had (the other being mechanic) and couldn't take dealing with mad customers at the ticket counter. I asked to be demoted back to working on the ramp. Dumping lavs was more dignified than dealing with angry passengers at the ticket counter or gate.
