Because many third part services require a phone number and will post that phone number around without permission.

I have a restaurant and we don’t offer phone service at all, phone goes to voicemail which tells you to send an email or order online.

I posted the number nowhere, but guess what, apple maps requires a phone number, uber grubhub dd require phone numbers, and lo and behold my fucking pos was posting the number on my website without my permission and gave me no way to remove it until I called repeatedly and complained, but even then it still pops back up sometimes.

Edit sorry I replied to the wrong person and im too lazy to change it 😬

Haha that’s the neat part
