The French existentialist Jean-Paul Sartre was sitting in a cafe when a waitress approached him.
‘Can I get you something to drink, Monsieur Sartre?’ she asked.
Sartre looked up from his reading and replied, ‘Yes, I’d like a cup of coffee with sugar, but no cream.’
Nodding agreement, the waitress walked off to fill the order and Sartre returned to his book. However, the waitress returned a few minutes later with a concerned look on her face. ‘I’m sorry, Monsieur Sartre,’ she said, ‘but we are all out of cream. Is it alright if we make you coffee with no milk?’
I always think about this joke when people say they’re going to boycott a place they never were going to shop at in the first place.
