I got an oil change 3 days ago. Today i found out there's a hole in the hose that goes to the water pump. Could this have been caused by a mistake from the mechanic changing my oil?

What is your question?

I noticed smoke coming from the hood of my Escape as I was driving today, 3 days after the oil change. I pulled over, noticed liquid on the engine and oil cap, and some leaking from underneath the car. I called the shop which happened to be nearby. Mechanic came to look at it, said it was a coolant leak, likely from the hose. He okay'd it for me to drive to the shop so he could take a better look at it. Got a phone call later saying sure enough, there's a hole in the hose that leads to the water pump... a $255 +tax repair. I told them not to touch it. My question is if it's possible that the mechanic could have caused the issue whether by accident or on purpose, or if it's likely that it was already damaged before the oil change.
