Phrase to say when you are interrupted

Me

Today, I was interrupted by the customer at the cashier of the store.
So I thought “In this case, what should I say in English ?” Then I researched
I quickly found various expression

For example,
“Could you get in line, please?”
“Don’t cut in!”
“Get in line!”

I guess “Could you get in line please?” is the safest.

Yes I agree. That expression is the most polite way to say so.

割り込みされた時に、かける言葉

今日、店のレジで割り込まれたんで、「こんな場合、英語では何て言うんだろ？」と思って調べたら、すぐに見つかった。
色々な言い方があるもんだな。

“Could you get in line, please?” が一番無難かな。
