I work for a piano tuner, who is Russian. He, therefore has several Russian-speaking clients. I called one today. (Looked at the phone number, not the name.) I was totally unprepared!
Here's my spiel in English:
Hi! My name is Christine. I am calling for Dmitriy Last Name, who tuned your piano over a year ago. Since pianos should be tuned every year, I was just checking to see if you want your piano tuned.
Here's what I've got so far:
Алло! Меня зовут Кристина. Я работаю для Дмитрия. Он настроил ваш пианино (или рояль) один год назад. (Then I skip the part about pianos needing to be tuned annually because I don't know how to say that.) Вы хотите чтобы Дмитрий настраивать
ваш пианино?
Then, if someone says "Yes". I have to schedule a date and time! I can do that in Russian
I can also say how much it costs
