Glottal stops bug me too.
Also, people who say oways instead of always.
Just because English has a lot of silent letters doesn't mean you can randomly choose which ones that are.
As you pointed out that's just accent, and hardly random.No I mean the glottal stops that are prominent in certain accents. Watch any video with Ricky Gervaise. He doesn't pronounce the letter "T" unless the word begins with it. Instead he'll make the sound where the T should be in the back of his throat.
Or certain American accents - for instance people who use a glottal stop in the phrase, "Oh no s/he dih-unt," instead of the letter "D".
(And believe me, I'm no fan of glottal stops: it's not pleasant to come to England when your first language is not English, and realise teachers forgot to mention most t's you see on the written page are just passé, and you have to develop an ear for that before your year abroad is finished...)
