I ask for no ice because pop is pretty cold when it comes out anyways and I hate watered down pop. Also if I take it home I can put it in the fridge .... and it doesnt get watered down.
Some folks have noticed the service you get in the States is shit, unless the wait staff identify you as someone who will give a good tip. If you're from an ethnic group notorious for bad tipping, you're never going to get good service, and so you're never going to tip well... Continuing the cycle. 🤷🏻♀️
It's not that it'll clean better, but an additional rinse can't hurt - especially if a utensil might have been crowded or rushed through the wash. Or maybe the waitstaffs hands are a bit suspect.
