A few incidents come to my mind:
1) I got sick while staying at the Plaza Athenee in Paris about 10 years ago. Nothing too crazy, but I was in the mood for chicken soup (jewish penicillin). My wife went to speak with the concierge to see what could be done (this was before uber eats, etc). About 45 minutes later, there was won ton soup delivered in the hotel's normal fancy room service style. Not exactly my grandmother's homemade soup, but close enough! The hotel did charge me for the food (totally fair), but waived the room service delivery fees and included tea
2) I had a very bad allergic reaction to shellfish when in Rio and did not have an epi pen on me. At 2am on January 3rd, the Fasano got a doctor there within 30 minutes. The doctor demanded payment in cash in real which I did not have. The front desk agent charged my room and paid the doctor directly
