Desear

Could someone help me out here? I’m on second level and encountered this phrase:
¿Qué desean comer? - what would you like to It?(formal)
Why it’s not ¿Qué desea comer usted? In polish translation the original Answer shows there IS only one person asked. May it be incorrect translation? I mean that It should translate to plural?
