Have you ever

Have you ever visited one of those fast food chains, order your food, and the clerk asks you, anything else? I wonder, do they think we are stupid with an IQ of 3 that we need reminder to buy another thing, or that they are? Or that we had so much fast food that we forgot what we need to order???

I am confused .... Can't figure this out.... But very angry when I go to get coffee at drive thru and they ask .. Anything else ?
