I'm going to leave a cart of groceries in an aisle and walk out of the store
Did you feel bad for leaving this cart of groceries?
Not really; the store probably expects me to do this.
You should put your groceries back if you don't want them. Someone could trip over them. It blocks others and the grocery store frowns on this.
You're too serious. They will be okay, they pay people to put things away.
Leaving the cart just seems wrong though. The cold items could end up going bad. There is going to be an employee who is forced to put all the stuff back for you who already had other work to do.
