My thoughts are: if you bring it to a gun show and put it on your table and don't want anyone to touch it, then get the hell out of the show and go to a museum.
Sure, I understand that there are a lot of idiots that get grab-happy and there are those that try and steal stuff, but you've got to come up with a more customer-friendly approach (a glass case where you have to ask is a good idea).
Lots of our vendors on this site aren't rude and manage to handle their customers with good rep-or - and folks have been doing it for years at W and other shows. Just seems like everyone's getting more and more gripey about it every year and it makes me walk away from the show gripey.
This! x1000
Especially the collectors who have 500 Winchester 1894s made in 1894, priced at ONLY $5k each, and they're all "one of a kind" and they have huge "do not touch" signs, but the guns are hanging 12" into the aisle. WTF?
