This is based on my experience visiting Bali, Indonesia, recently.
I was on holiday in Bali and stayed at Sense Sunset Seminyak Hotel and got a room on the top floor.
The hotel has a U-shaped design. If you stand on the balcony, you can see the swimming pool on the ground floor. This is what it looks like:


A group of Indian men in their 40s were hanging around the pool wearing thin boxer shorts, no swimwear and smoking incessantly.
Then some Korean girls came wearing two-piece bikinis and got into the pool. Suddenly the men jumped into the pool wearing only their underwear and broke the underwater lights.
Security was immediately called and everyone got out of the pool. The Indian men were very noisy and almost all the guests came out of their rooms to the balcony to witness the incident.
I went down to the pool half an hour later and saw a notice board that the pool was closed. I asked the receptionist and was sad to hear the receptionist say that the guest from India had broken the pool light and the pool was closed to avoid electric shock. I went back to the room and felt very embarrassed.
On my return flight from Bali to Mumbai via Air Asia Indonesia, I again saw some Indians continuously harassing the cabin crew for silly reasons. I finally understood why flight attendants hate flying to and from India.
