There are many traits that are prevalent amongst engineers (there are plenty of jokes about this, normally told with glee by lesser humans), but i think there is possibly only one which appears to be universal:
We love free food.
Most engineers are honest people, who are not open to corruption, but they will do things for food that they would never do for money. As a result, it is common practise for equipment suppliers to come in to our offices to present “lunch and learn” sessions. While these sessions aren’t going to sway us to use a certain product (we are generally, after all, technophiles, and will always go for the technically superior product), the mention of a free lunch does ensure that the vendors get a room full of engineers who are too busy eating to ask annoying questions.
After these lunch and learns, we will discuss the merits of the presentation amongst ourselves: starting with the quality of the food, then on to the quality of the equipment being demonstrated.
But when you get engineers doing technical evaluations on food… weird things happen…
I was telling my wife about one such Lunch-and-learn, and the duck & coleslaw bagel that I ate:
“You know what the best thing about a good bagel is?” I asked her, as we ate dinner.
“What?” She asked, and really should have known better.
“The bit in the middle where there is a hole in the bagel, but the filling continues… actually, there’s probably a graph for that…” I mused.
“You don’t need to graph it, baby” she said, wishing she wasn’t just dead wrong.
“Oh yes, my little turnip. Yes I do…” I turned to the whiteboard on our kitchen wall…
I present to you… The Bagel Graph
(Filling as a ratio to bagel bread. Apologies for the quality of the graph, I tried to sketch it as neatly as I could on my smartphone).
