If you think that's bad, how about having your entire vacuum collection on display to the general public 365 days per year. I'm constantly making people stop touching the vacuums in the Vacuum Cleaner Museum. People will turn them on when my back is turned. I'll say "That's 100 years old, there are no parts available, and it will cost you over a thousand dollars to replace it".
Kids are the WORST. For the most part, the parents keep them from touching (and destroying) the museum exhibits. But some parents just do nothing while their brats tear things up. I've never had to ask someone to leave, but I have asked that they take their kids outside.
Interestingly, I just hosted a Vacuum Cleaner Collectors Convention at the Museum, followed by a barbecue at my home, with multitudes of little items (like air-way playing cards, Electrolux banks, etc.) laying around. Not one thing was broken or stolen. Then again, I don't allow just 'anyone' to join the Collectors Group. I'm personal friends with each person who attends a Convention, and I know where they live (just sayin). I see no good reason for an "all inclusive" club, and so I don't belong to one. Problem solved.
