Drop 'em at your peril

Looks like the Ticos also subscribe to this minor aberration in la lengua castellana...the noisy H. 

Other examples of the not-so-silent treatment that one comes across around here are in silly names of foreign derivation - such as Heniferth - or in place names like El Hato. 

Drop any of these 'haitches' in LAG and you will tend to sound like a bit of a tit.
