<human>: Can you condense the text into a few key points?

OK, I was in Epcot resort in Disneyworld a few weeks ago. Here I am in Japan looking around the gift shop for a nice souvenir. Bonsai? nah... But a fan and fancy $12 chopsticks? Hell yeah. So I grab the fan and chopsticks and proceed to the checkout line. There are 2 registers; one has 1 person while the other has a bunch. I didn't see this until I was halfway done in my line with about 5 people left, all only kids and their parents. So I imminently think, "just two people? not a problem" After they're done checking out, I walk up to the 2nd register and proceed to give the cashier my souvenirs. She then politely told me that the two lines merge into one. I say sorry and go back to the end of the real line, which is now 10+ people. One of the kid's dad felt bad for me and let me cut in front of them. (His son does not see me at all, too fixated on his Pokémon cards) So after the guy in front is done (not the dad and son), I walk up again. She says, "Sir, **there is** a line. Then the kid tells his dad (the same dad who let me cut inline, btw) "why is cutting in front **again**?" I felt so bad that I just walked all the way back to the now 20+ people line with all the parents giving me dirty looks.
<bot>: I cut inline at a gift shop in the most magical place in the world and made a little 8 year old upset.*
