Was in a LGS a few days back. Another fellow was trying to talk to an employee about different revolvers in the showcase. Within earshot was a local "self appointed expert" who "knows(?)" more about any gun (model, performance, history, etc.) in the store than the people working there. The guy keeps interjecting his "expertise" and won't hush. How do you folks deal with a situation like this without getting "ugly"? 
"Tact" is a word I heard once, but never learned how to use it!
