I expect this case is more like "upset," and I think there are four 
important rules.

1/ Is it being used as a noun, adjective, or verb?

2/ It may be done differently in England than it is in the colonies, but 
you can't count on it.

3/ No matter which way you do it you are certain to upset someone.

4/ If you do it both ways you may appease everyone, but more likely you 
will upset everyone.

HTH,
(I vote for two t's.)
