Sorry, but this is just a staggeringly awful FirstWorldProblems/Karen kind of thing. I mean, sure, maybe that's the worst part of your "office job" (which I'm guessing is, like many people here, a six figure development position in a career you genuinely enjoy), but you say that because you've never had to be on your feet for 8 hours straight bagging groceries or emptying trash cans or entering orders from cranky customers into a POS terminal.
Good grief. Bad training meetings are what you choose to complain about? Really?
