from the other day, on the phone:
me: i'd like to order a pizza for carryout.
her: pickup or delivery?
her (very uncertain): uhhhh.... delivery?
me: okayyyy, pickup.
her (back to normal): okay!
maybe i'm being naive, but i'm rather under the impression that a pizza phone answering job 1) isn't terribly complex, and 2) has a rather limited jargon set. there are really only four terms for describing three options for accessing the pizza: dine in, carryout, pickup, delivery. MAYBE takeout, for those used to ordering Chinese.
this isn't even a training issue! and i will cite not-a-language-barrior, as the order-taker was a white teenager from the chicago suburbs.
these are the people who will be running the country when i'm retired. egads.
