The sum of all fears

(13 missing because of classic superstition. 4/14/24 missing because “4” sounds like “death” here in Taiwan. 2 missing because the lobby is tall.)

@mwichary Others have pointed out that they didn't skip B4, but why did they skip B1? (Another really tall floor?)
@snowfox Might be. I also wonder if people might press B1 expecting 1? Just a speculation. Contrary to America for example, I haven’t seen a universal symbol like asterisk to denote the “exit floor.”
