Years ago when I worked at Taco Bell someone got fired because the manager walked in on him snorting coke off the bags of strawberry they used to put on top of the fruitista freezes in the walk-in.
Also some asshole pulled a gun in drive thru during my shift because he ordered extra cheese on his 7 layer nachos and apparently did not get adequate cheese.
Honestly in a use case like family photos, redoing it every x amount of time is probably a good idea anyway so new ones can be added.
