For large spaces there's more considerations than more person-sized spaces. If you make your theater or restaurant comfortable when it's empty and people are walking in, you'll need much bigger AC gear to catch back up once everyone's in there generating heat. It's one of those cases of a problem being quite a bit harder than you might intuitively think because for the most part, engineers have just solved it for you in most spaces, but there are some places where it just gets too hard to fully solve. Variations between locations are probably accounted for in differences in code and how much money there is to spend on the heating and cooling gear, plus how much variation there is in the outdoor weather.
IIRC a person can be approximated as 100 watts of heating. If you add up everyone in the full restaurant or theater you get quite the number for how much heat the people themeselves are putting out.
