Who’s Worse: The Customer For Calling Or The Coworker For Encouraging It?

I had a customer that my coworker was friends with, and I used to see the customer outside work. She’d say hi and ask how I was doing or whatever.

One night, at like 7:00 pm, I got a call on my cell phone from an unknown number.

Me: “Hello?”

Customer: “Hi! This is [Customer]! I’d like to order some items…”

My coworker GAVE THIS CUSTOMER MY PERSONAL CELL PHONE NUMBER! She was trying to order stuff while I was AT HOME.

I blocked her number. The coworker who gave her my number had already quit so nothing could really be done work-wise.

The customer very much avoids me in public since I blocked her.
