Kunikida is a drive-thru Order taker.

                ━°⌜ 理想 ⌟°━

You can hear him yelling at Dazai in the backround for a moment. Because he was flirting with a customer AGAIN.

"Hello, welcome to McDonald's ; How may i help you?"

He tries to sound as polite as possible, but Dazai just made his tone sound frustrated. Making it impossible for him to take orders politely.
