If I could put zero and even less I would have done! Being literally put out because we just wanted to order desserts is just aberrant.
Nobody told us that we were
supposed to have dinner to order desserts. We were seated and warned the waitress that we wanted to order only desserts (it was 22:30). Instead of telling us directly that we had dinner to order desserts, she went directly to her superior who was eager to hunt us! The people who accompanied me, had already been in their establishment to consume only their desserts. We were really surprised and for my part shocked! I wanted to start a discussion calmly to show the stupidity of the thing but the superior followed me very closely to get me out as soon as possible. It is an establishment to avoid! We treated as less than nothing and that's just intolerable! Never in London have I been treated this way.
