I've tipped occasionally on these, but I've stopped. For anything transactional, I'm not leaving a tip. Having a waiter at a table has some relationship component to it, tipping makes sense. Choosing how much you value the meaningless 5 second interaction you just had with the person that took your order is ridiculous - if they want to add a service fee, fine, but the very fact that you're choosing how much to give them renders the whole thing pointless.
