<human>:  Why did the riots start in the recent riots in Athens hotels?
<bot>: The riots started because the Greek government raised taxes on hotel rooms. The government was trying to raise money to pay off their debt. This caused the price of hotel rooms to rise, which made it harder for people to afford to stay in hotels. The government also tried to pass a law that would require hotels to pay a tax for every guest. This would have been a big burden on the hotels, so they protested against it.
