Dar vienas galimas variantas - Front of House Assistant. Angliškos Receptionist pareigos lietuvių kalboje dažnai verčiamos kaip Administratorius (-ė). Todėl, jei šio asmens pareigos yra pasitikti klientus ir nukreipti juos tinkama linkme, patarti, padėti, parodyti, paaiškinti ir pan., tai siūlyčiau būtent šitą variantą.
