I've had a couple bad experiences with "pros" lately.
I'm a smart guy and/but I'm also diplomatic. If I think I can help the situation, I try to do it without insulting the experience of the "pro."
I ran into a friend at a park who had locked her keys in her car. The tow company guy had already been working on it for a good while and was having a hard time getting it unlocked. he had a thing inspired by a blood pressure cuff stuck in the door frame to give him room to get a big gumby-doll like stick in there to trip the lock on the passenger door. I peered in from the driver side when he got the lock tripped. But the door would not open when he pulled on the door handle. My first though, and I offered this up to the "pro" was "I think if you take the presssure out of that thing, it'll pop right open when you pull the handle."
The guy just shook his head and continued going at the lock and calling folks on the cell phone expressing his frustration.
After a few minutes, I once more said, "I REALLY think that if you just release the pressure on the door frame, it will open right up." The guy kinda shrugged, twisted the valve to let the air out of the bag and tried the handle...it popped right open. The guy did not say another word to me...he just packed up his stuff, got in the truck and drove off.
The other was a dumptruck driver. In my eperience, dump truck drivers are generally pretty good at backing up trucks and putting loads exactly where they want them. This old codger, on the other hand, simply could not figure out how to back a truck along a fenceline. I tried to help guide him (at first he seemed receptive to it) but he just wouldn't do what I told him needed to be done.
He went back to the quarry with a a full load of gravel (what...16 tons or so?). I really wanted that driveway, too! Oh well...I just need to find someone who can back up a truck, I guess.
