Worst customer service at Le Monde Cafe

The worst customer service I ever received was at this little place. There are clearly house rules as to who is allowed to sit out on the patio and who isn't, but no one lets you know until you've ordered. Then they tell you (correction - they Order you) to move inside (when you've clearly come to enjoy the patio, and have been sitting there for good 40 minutes) because there are people who want to smoke hookah. Why should I care, I was here first!?! There are 3 other free tables on the patio
