Is the kind of thing Gerald Cooper would say, only there’d be a reference to dry stone walling thrown in.
Yep that'll have been their argument........I once had a stand up argument in the check in line with a "supervisor" at Manchester airport for 45 mins saying I couldn't have my normal clothes together with my snowboarding gear in my board bag even though the bag was 2kg under the weight limit because it would unbalance the plane. The argument went back and forth with her trying to get me to pay an extra charge (even though I was under the limit), then trying to get me to buy an additional suitcase to put my normal clothes in, then her suggesting she got some black plastic bin bags to put my clothes in (to which I just laughed in her face citing the care that baggage handlers use) and so it went on back and forth. I was even prepared to wear every single item of clothing to shut the stupid bitch up.........then when she brought out the "balancing the plane" argument I pointed to the guy stood behind me who was about 25 stone and 6'7" and asked how she was gonna deal with him given he was a good 70kg heavier than me and my board bag combined. After 45 mins I won the argument to the cheer of the ever growing line of passengers behind me that they'd held up for 45 mins, and they checked me in.
that's a good story, and well done for standing your ground and thinking quickly on the spot which I know that I certainly wouldn't have had a hope of doing, also good that the chap behind you didn't take offence when you used him as an example!
On the subject of striking a pose for archeologists to find you in, once they chip through several feet of ash and pumice, the only one I could think of is taking a shit in the middle of the street.
