I travel a lot for work. As such, I eat out a lot. As such such, I look at a lot of places’ menus without physically being there (since I don’t know the area, I don’t know where to eat, so I look at the reviews and images posted online).
A restaurant’s soup selection will likely not be the thing that decides if I eat there or somewhere else, but sometimes soup is the only side dish that sounds appetizing, and if I don’t know what kind of soup the restaurant serves I’ll probably just pick somewhere else.
Reminds me of a customer complaining, “no, I’ve had soup du jour before and this is not it!!”
Also from Dumb and Dumber:
“Excuse me, what’s the soupe du jour?”
“It’s the soup of the day.”
“Oh, that sounds good, I’ll have that.”
