What makes you think they won’t? How much is it worth you when you’re feeling miserable to have a nurse that checks on you every 10 minutes instead of every hour? How much gratitude do you have for personal attention when you need help rather than just carrying food to a table?
And like all places that transition to tips, they probably won’t just say “we take tips now, -$10k”, they’ll first add it as an option for “an extra thank you” that then becomes factored into the salaries they offer to new nurses and the raises they give to existing employees.
