I sometimes skip the beginning letter of a word so I can say it

I sometimes skip the beginning letter of a word so I can say it Like when I'm at Jamba Juice and I order the Mango Madness.. I just say Ango Madness, I try to order it real fast so they won't notice. Also at stores, when they ask me Debit or Credit? I always ebit :( It's kind annoying, but I guess whatever works to get past my blocks. I sometimes do this a lot at the drive-thru, they can't really understand me anyway so I go ahead and skip a letter. Anyone else do this?
