How stupid can a beauty salon owner be to create this setup?

I went to a salon for a haircut. Each chair had, of course , a mirror in front of the chair but on the side of each mirror was a phone. I think it was meant to “impress” the customer because the phone kept ringing and the person cutting my hair would stop and talk on that phone about making them an appointment. I’d be mid-sentence and the phone would ring, she’d stop and chat with the caller about their hair. Is this dumb or what? Or would you go back?
