On the boredom front I used to work at a few art fairs, 4 or 5 days of back to back ‘private views’, morning noon and night. The set up is enough to exhaust you, but you have to sparkle, charm and try and hoover money out of drunk people’s pockets. The novelty wears off incredibly quickly and booze makes looking interested becomes harder and harder to do, you get foot-sore and just holding your own head and shoulders up becomes more of a challenge than it should.
I wandered into someone elses stand and the proprietor was in the corner, he had a quite stretch and yawn, with the yawn ending in the loud announcement “chrrrrrrist I’m bored!”. Sufficiently loud to silence everyone around him, before timidly adding “sorry, did I say that or just think it?”
