In this classic scene Harry is just relaxing, trying to eat his goddamn hotdog in piece but some armed robbers have other plans and interrupt his lunch. Not cool.
It’s funny watching the scene now and you forget how calmly Eastwood delivers the line; it’s not until the end of the movie where he says it more aggressively to the villain Scorpio. We need more bad guys with names like Scorpio FYI.
Anyway I love how Harry smiles throughout; he just loves messing with people and this is why he remains the best movie cop in the business.
