After we saw this happen, my travelling companion and I pondered if the fault was with the exhibition design, graphic design and/or copy writing... and well... There were clear and large panels either side of the object, offering both long hand and bullet points, and also illustrations. A great deal of effort had been spent to make it clear that although it looked like one, this was not a sarcophagus. 

The visitors couldn't have not seen those panels given the time they took around the object, and if the long hand looked too much like a wall of text for them, they had the option of the bullet points, or drawn illustrations which showed the object in use. The gent's tone of voice and (longer than quoted here) questioning, implied frustration at a lack of explanation, rather than confusion over the very clear explanation given. We concluded that they are perhaps among that pool of inevitable visitors who are genuinely able to reach around a Do Not Touch sign, and touch something, without having ever realised they have been in contact with a Do Not Touch sign.

Simple solutions: When you have a display plinth too large to balance on the trolley, use a counterweight! What should you use as a counterweight? Whatever is to hand and safe really....

I asked if I should, said that I wouldn't, then realised what a great wealth of information is shared there.
