$200 for water spilled, seriously that is pretty poor and over the top. A sincere apology from the FA and Head FA, and more freely flowing drinks for the rest of the flight should really be all that occurs. It's water and unless it was a very expensive silk jumper or something it's over the top. If it was a sticky drink or alcohol then it's different, but it was water!
On the other hand, if IFE or a seat is not working properly in C or F then more like $1000 should be forthcoming!
