Hi there
No one ever expects to use OOA skills, rescue breathing, CPR, tired diver tow and the like. Like insurance we learn these things hoping to never use them. You however found the value early of learning these skills and stopped a potential problem before it escalated into something worse and your actions did exactly what they were supposed to accomplish. As you may know most of the problems with diving occur on the surface. I have seen my share on the surface as well as below and everyone is here to enjoy another day of diving in the watery wonders, thanks to you the same can be said for this occurrence.
