I don't recall this question being asked before.
When you go out to do a photo-shoot, whether it be birds, portraits, landscapes, street or any other genre, do you take something with you to eat/drink, or do you buy something while you are out and about? Perhaps you go for breakfast to a favourite place after a sunrise landscape, or stop for a coffee and a pie after birding?
Tell us what you like to do for sustenance when you are out taking photos.
