It was night and holiday lights twinkled as shoppers bundled against the cold and moved about.

But, of course, being a person in the HVACR industry, my thoughts turned to more practical matters, such as, “Is it really a good thing for a supermarket to let in a lot of cold outside air?” I guess it would be good for the refrigeration equipment as outside ambient would help take the load off the mechanical cooling. But what about the rest of the store where customers need some heat in Chicago in late November?

I suppose there could be some heaters over the entrance way but I didn’t sense their presence in the movie — and isn’t that a pretty costly way to control climate in the store versus some automatic doors like you typically see in a supermarket?

I muttered these musings to my wife as we watched the movie, but she kept hushing me because this was the critical point in the film when the good-looking guy and good-looking girl were starting to discover vulnerabilities in each other that would eventually lead to love.

And I guess in these movies, love means more than economical mechanical refrigeration systems.
