Thailand has this annoying country wide festival called Songkran where people randomly spray you with water. It's annoying because their water is not treated so it's dirty, can cause eye irritation and skin. It's supposed to be 3 days but the gov has extended it in some places to attack tourists.

There is a high amount of accidents and issues during that year too.

I went there a few years ago and got sprayed. I'm going back this year but made sure it's not during that time period, which is currently happening at this moment.
