Okay, not trying to be "snobby", but...

It would be wrong not to write such a letter. You are making an effort to see no other smokers have the same problem in the future. You are speaking out for the guy who may be too timid or lazy to. You, sir, are a hero!
I'm a hughazzz fan of both brands of cigars and your effort today may save even the likes of me from dealing with the horror of a ginormous stem in his stogie. For that I thank you!

As for Wayne, if he wants to replace the cigars I'd let him. And if anything, Ashton might send a few boxes gratis to Wayne's store because of yr letter.
