They absolutely do. I always give a fair warning before the interview as well, but generally haven't had a problem. Working with customers, phone calls, etc is horribly terrifying at first, but I've learned to just roll with my stutter rather than focus on it. Most people aren't giant assholes, so I've rarely gotten "called out" on it. It's happened, but I'm just there trying to pay my bills, and if a customer has an issue with that, then their opinion doesn't matter, frankly. Just my two cents worth, though.
