They had a funny rule in the Vatican exhibit: photos were okay but no selfies. I could stand in front of an artifact and have someone take a picture of me, but I could not take a picture of myself.
I asked one of the docents about the reason for that. “Does it detract from the holiness of the enterprise or what?”
“No, people taking selfies tend to lose track of their surroundings and start banging into the art.”
I bought a souvenir T-shirt for $32 in the gift shop. They made me sign the credit card slip, even though a lot of places trust me for amounts under $50.
“Trust but verify” as President Reagan himself used to say.
