Breakfast is definitely a bummer no doubt, but for a hotel which costs 1000 EUR per night in the summer, if we have to spend 50 EUR extra per couple for breakfast it's not something hugely material in the grand scheme of things (5% only), therefore it would not lead me to say "I am not welcome anymore" unless there were other service issues during the stay. This is what I would like to know - is there is something else going on.
