Use of bean bag

[Theisey]

Ted,
I'm taking the exact opposite position on your question.
You study the rules hard and you follow them as best you can. That all pays off when it comes time to make the move up the ladder. Same goes with mechanics, you should study them just as hard if not harder and that includes proper use of a tool call the bean bag.
It demonstrates you know what you are doing when you use it properly. To just toss/drop/throw bean bags about for no purpose shows the official is clueless when it comes to mechanics. It takes no time to figure it out. You'll make a few errors along the way, but you'll be getter off in the long run.
There are maybe only ten situations to drop a bag, learn them and use the bag only in those situations. Bad habits should not be tolerated.

The next time to see the ref toss a 10-yarder on a QB muff of a snap, you can at least sit back and say "he has no clue".
