I'll summarize the answers the question received in the comments: 1) perhaps the bathroom water is ok to drink 2) ask the helpdesk 3) Buy water.
- In the bathroom? – JonathanReez♦ yesterday
- Ask at any convenient customer service desk – Peter M yesterday
- Suggestion: don't, just take the hit and buy a new one. – user253751 Mar 15 at 18:01
