I can certainly relate, as I was umpiring a sectional game in Glassboro about a decade ago for the Little League Intermediate division (13u on a 50/70 field). I was doing the bases, and a kid hit a solo Home Run to left with no one on, and missed first base by several feet. The 1st base dugout was the defensive team, and as the kid was rounding the bases, that dugout is yelling to me "I hope you were paying attention blue". They did appeal missing first, I called the kid out, and all hell broke loose. The 1st base coach obviously didn't see it, but his argument was that I needed "be the star" and I'm "making sure everyone sees me".
About two innings later, the same team hit a solo HR down the right field line. I went out on the play so my plate ump was covering the touch at 1st, but the replacement 1st base coach (the original 1st base coach got ejected on that 1st HR) starts going off on me that I'm not even paying attention to the guy touching 1st because I'm watching the ball and I obviously never saw the missed touch on the first HR.
After all the crap I put up with that night, I vowed to never again work a game for free, and I've never done a sectional/state game since that night.
