Audio is probably faster per person. However, it is serial in nature. I walk up to 4 kiosks and want a combo #3 with a coke, and I get to skip the three families, each trying to talk their 4 year old into choosing fruit and milk over fries and a coke. Also, order verification is nice with a kiosk (for now). If I want something without pickles, I can see that right in front of me. It seems like every drive-thru and PoS that has a display which can provide order feedback has switched to displaying ads to buy some other product. I'm sure it's just a matter of time before the kiosks start to have modals which have to be cleared to continue with the order: Have you tried the hot apple pie? How are you enjoying the kiosk experience? Really, the people doing these things can never resist.
