Sister's experience with phone call from Chinese restaurant

My sister and her boyfriend came down for supper they’re buying the family (Mom, Dad, and I) Chinese food… I don’t know what time they expected to get here but they got here 30mins before my Dad’s virtual appointment. When they were in the boyfriend’s car- they ordered the Chinese food and a woman from our Chinese place (who obviously wasn’t the owner, the wife, or their daughter) called back saying “the food would be ready in 25mins” and my sister said “I asked for it to be later” and the woman said “I didn’t notice that”.
