I am not an eloquent speaker. It seems like my brain goes too fast for my mouth, and the result is not that I am a fast speaker, but that my words smash together like a ten car pile-up on the freeway. Usually this happens rather infrequently: mostly when I'm nervous or have something I'm particularly passionate about on my mind. But I find that the more that I speak, the more often this happens.

It is therefore a misfortune that I am a cashier and that I am, in fact, payed to speak to people constantly. A conversation that should go like this:
Mbr> Me: Hi, how are you today? (pause)What can I get for you?
Customer: A taco, a side of rice, three bean burritos and a number three.
Me: alright I have a taco, a side of rice, three bean burritos and a number three, for here or to go?

Often ends up something like this:

Me: HI! How'reyou today? (pause) What can I get for you?
Customer: (blah blah blah)
Me: Kay, I have a tacosiderice, three bean burritororos, I mean burritos and a numbahthree, forhereorgo?
Customer: what?

Sigh. I would typically not mind, except that it makes me seem less intelligent than I am, I think, and flustered...which I'm not really. Just.. a weird speaker. Grr.

This 'speech impediment' as I refer to it in my head is 20% of the reason I don't ever give witty comebacks--because when I think of them, I know that I will mess them up. The other 80% us just me being slow witted. XD
