Whenever I get close to a JIB, my android phone gives me an alert that says JIB is a popular photo opportunity.
My advice is if you need a pic of the JIB menu, just do it! If Google thinks it's normal for people to take pics of the JIB interior, then the JIB employees probably think it is normal too. Trying to bee too convert in taking pics often makes you look suspicious. How long does it take to snap half a dozen photos using the volume buttons on a smartphone? Answer: I get about 6 or 7 shots in a second. After taking the bracket shots, I go into the restroom to take pics there, and I check my menu board photos to see if I have at one good one. In the unlikely that none are good, then I can always pause another second to take another half a dozen shots of the menu board.
